test: dm: Fix wrong aliases property names After importing v4.17-rc1 Linux commit 9130ba884640 ("scripts/dtc: Update to upstream version v1.4.6-9-gaadd0b65c987"), sandbox build reports below warnings: arch/sandbox/dts/test.dtb: Warning (alias_paths): /aliases: aliases property name must include only lowercase and '-' arch/sandbox/dts/test.dtb: Warning (alias_paths): /aliases: aliases property name must include only lowercase and '-' arch/sandbox/dts/test.dtb: Warning (alias_paths): /aliases: aliases property name must include only lowercase and '-' arch/sandbox/dts/test.dtb: Warning (alias_paths): /aliases: aliases property name must include only lowercase and '-' Silent them by applying the 's/_/-/' substitution in the names of the 'fdt_dummy0', 'fdt_dummy1', 'fdt_dummy2', 'fdt_dummy3' properties. Similar DTC warnings have been recently fixed in Linux kernel, e.g. via v4.17-rc1 commit d366c30d19f4 ("ARM: dts: STi: Fix aliases property name for STi boards"). If done alone, the DTS update generates a failure of the `ut dm fdt_translation` unit test in sandbox environment as seen below: $ ./u-boot -d arch/sandbox/dts/test.dtb ---<-snip->--- => ut dm fdt_translation Test: dm_test_fdt_translation: test-fdt.c test/dm/test-fdt.c:444, dm_test_fdt_translation(): 0 == uclass_find_device_by_seq(UCLASS_TEST_DUMMY, 0, 1, &dev): Expected 0, got -19 Test: dm_test_fdt_translation: test-fdt.c (flat tree) test/dm/test-fdt.c:444, dm_test_fdt_translation(): 0 == uclass_find_device_by_seq(UCLASS_TEST_DUMMY, 0, 1, &dev): Expected 0, got -19 Failures: 2 ---<-snip->--- Fix this issue in place, by updating the "name" string in the UCLASS_DRIVER(fdt_dummy) definition, so that it matches the newly updated aliases properties.

fdt: translate address if #size-cells = <0> The __of_translate_address routine translates an address from the device tree into a CPU physical address. A note in the description of the routine explains that the crossing of any level with since inherited from IBM. This does not happen for Texas Instruments, or at least for the beaglebone device tree. Without this patch, in fact, the translation into physical addresses of the registers contained in the am33xx-clocks.dtsi nodes would not be possible. They all have a parent with #size-cells = <0>. The CONFIG_OF_TRANSLATE_ZERO_SIZE_CELLS symbol makes translation possible even in the case of crossing levels with #size-cells = <0>. The patch acts conservatively on address translation, except for removing a check within the of_translate_one function in the drivers/core/of_addr.c file: + ranges = of_get_property(parent, rprop, &rlen); - if (ranges == NULL && !of_empty_ranges_quirk(parent)) { - debug("no ranges; cannot translate\n"); - return 1; - } if (ranges == NULL || rlen == 0) { offset = of_read_number(addr, na); memset(addr, 0, pna * 4); debug("empty ranges; 1:1 translation\n"); There are two reasons: 1 The function of_empty_ranges_quirk always returns false, invalidating the following if statement in case of null ranges. Therefore one of the two checks is useless. 2 The implementation of the of_translate_one function found in the common/fdt_support.c file has removed this check while keeping the one about the 1:1 translation. The patch adds a test and modifies a check for the correctness of an address in the case of enabling translation also for zero size cells. The added test checks translations of addresses generated by nodes of a device tree similar to those you can find in the files am33xx.dtsi and am33xx-clocks.dtsi for which the patch was created. The patch was also tested on a beaglebone black board. The addresses generated for the registers of the loaded drivers are those specified by the AM335x reference manual.

firmware: add SCMI agent uclass This change introduces SCMI agent uclass to interact with a firmware using the SCMI protocols [1]. SCMI agent uclass currently supports a single method to request processing of the SCMI message by an identified server. A SCMI message is made of a byte payload associated to a protocol ID and a message ID, all defined by the SCMI specification [1]. On return from process_msg() method, the caller gets the service response. SCMI agent uclass defines a post bind generic sequence for all devices. The sequence binds all the SCMI protocols listed in the FDT for that SCMI agent device. Currently none, but later change will introduce protocols. This change implements a simple sandbox device for the SCMI agent uclass. The sandbox nicely answers SCMI_NOT_SUPPORTED to SCMI messages. To prepare for further test support, the sandbox exposes a architecture function for test application to read the sandbox emulated devices state. Currently supports 2 SCMI agents, identified by an ID in the FDT device name. The simplistic DM test does nothing yet. SCMI agent uclass is designed for platforms that embed a SCMI server in a firmware hosted somewhere, for example in a companion co-processor or in the secure world of the executing processor. SCMI protocols allow an SCMI agent to discover and access external resources as clock, reset controllers and more. SCMI agent and server communicate following the SCMI specification [1]. This SCMI agent implementation complies with the DT bindings defined in the Linux kernel source tree regarding SCMI agent description since v5.8.

However this is not ideal, since every device on a PCI bus has a child device. This is only really the case for sandbox, but we want to avoid special-case code for sandbox. Worse, child devices cannot be probed before their parents. This forces us to use 'find' rather than 'get' to obtain the emulator device. In fact the emulator devices are never probed. There is code in sandbox_pci_emul_post_probe() which tries to track when emulators are active, but at present this does not work. A better approach seems to be to add a separate node elsewhere in the device tree, an 'emulation parent'. This could be given a bogus address (such as -1) to hide the emulators away from the 'pci' command, but it seems better to keep it at the root node to avoid such hacks. Then we can use a phandle to point from the device to the correct emulator, and only on sandbox. The code to find an emulator does not interfere with normal pci operation. Add a new UCLASS_PCI_EMUL_PARENT uclass which allows finding an emulator given a bus, and finding a bus given an emulator. Update the existing device trees and the code for finding an emulator.

fdt: translate address if #size-cells = <0> The __of_translate_address routine translates an address from the device tree into a CPU physical address. A note in the description of the routine explains that the crossing of any level with since inherited from IBM. This does not happen for Texas Instruments, or at least for the beaglebone device tree. Without this patch, in fact, the translation into physical addresses of the registers contained in the am33xx-clocks.dtsi nodes would not be possible. They all have a parent with #size-cells = <0>. The CONFIG_OF_TRANSLATE_ZERO_SIZE_CELLS symbol makes translation possible even in the case of crossing levels with #size-cells = <0>. The patch acts conservatively on address translation, except for removing a check within the of_translate_one function in the drivers/core/of_addr.c file: + ranges = of_get_property(parent, rprop, &rlen); - if (ranges == NULL && !of_empty_ranges_quirk(parent)) { - debug("no ranges; cannot translate\n"); - return 1; - } if (ranges == NULL || rlen == 0) { offset = of_read_number(addr, na); memset(addr, 0, pna * 4); debug("empty ranges; 1:1 translation\n"); There are two reasons: 1 The function of_empty_ranges_quirk always returns false, invalidating the following if statement in case of null ranges. Therefore one of the two checks is useless. 2 The implementation of the of_translate_one function found in the common/fdt_support.c file has removed this check while keeping the one about the 1:1 translation. The patch adds a test and modifies a check for the correctness of an address in the case of enabling translation also for zero size cells. The added test checks translations of addresses generated by nodes of a device tree similar to those you can find in the files am33xx.dtsi and am33xx-clocks.dtsi for which the patch was created. The patch was also tested on a beaglebone black board. The addresses generated for the registers of the loaded drivers are those specified by the AM335x reference manual.

The patch acts conservatively on address translation, except for removing a check within the of_translate_one function in the drivers/core/of_addr.c file: + ranges = of_get_property(parent, rprop, &rlen); - if (ranges == NULL && !of_empty_ranges_quirk(parent)) { - debug("no ranges; cannot translate\n"); - return 1; - } if (ranges == NULL || rlen == 0) { offset = of_read_number(addr, na); memset(addr, 0, pna * 4); debug("empty ranges; 1:1 translation\n"); There are two reasons: 1 The function of_empty_ranges_quirk always returns false, invalidating the following if statement in case of null ranges. Therefore one of the two checks is useless. 2 The implementation of the of_translate_one function found in the common/fdt_support.c file has removed this check while keeping the one about the 1:1 translation. The patch adds a test and modifies a check for the correctness of an address in the case of enabling translation also for zero size cells. The added test checks translations of addresses generated by nodes of a device tree similar to those you can find in the files am33xx.dtsi and am33xx-clocks.dtsi for which the patch was created. The patch was also tested on a beaglebone black board. The addresses generated for the registers of the loaded drivers are those specified by the AM335x reference manual.
