6da8400d7a clk: rockchip: rk3568: Fix mask for clk_cpll_div_25m_div
The field for clk_cpll_div_25m_div in CRU_CLKSEL_CON81 is 6 bits wide,
not 5 bits wide as currently defined in CPLL_25M_DIV_MASK.

Fix this and the assert so that CPLL_25M can be assigned a 25 MHz rate.

fd6e425be2 rockchip: rk3588-rock-5b: Enable boot from SPI NOR flash
Add sfc and flash node to device tree and config options to enable
support for booting from SPI NOR flash on Radxa ROCK 5 Model B.

Similar to RK3568 the BootRom in RK3588 can read all data and look for
idbloader at 0x8000, same as on SD and eMMC.

Use the rksd format and modify the mkimage offset to generate a bootable
u-boot-rockchip-spi.bin that can be written to 0x0 of SPI NOR flash. The
FIT image is loaded from 0x60000.

  => sf probe
  SF: Detected mx25u12835f with page size 256 Bytes, erase size 4 KiB, total 16 MiB

  => load mmc 1:1 10000000 u-boot-rockchip-spi.bin
  1492992 bytes read in 129 ms (11 MiB/s)

  => sf update $fileaddr 0 $filesize
  device 0 offset 0x0, size 0x16c800
  1300480 bytes written, 192512 bytes skipped in 11.103s, speed 137694 B/s

The BROM_BOOTSOURCE_ID value read back when booting from SPI flash does
not match the expected value of 3 (SPINOR) used by other SoCs. Instead a
value of 6 is read back, add a new enum value to handle this new
bootsource id.

bb52f1c604 reset: rockchip: implement rk3588 lookup table
The current DT bindings for the rk3588 clock use a different ID than the
one that is supposed to be written to the hardware registers.
Thus, we cannot use directly the id provided in the phandle, but rather
use a lookup table to correctly setup the hardware.

This approach has been implemented already in Linux, by commit :
f1c506d152ff ("clk: rockchip: add clock controller for the RK3588")

Hence, implement a similar approach using the lookup table, and adapt
the existing reset driver to work with SoCs using lookup table.
The file rst-rk3588.c has been copied as much as possible from Linux.

Adapt the clk rk3588 driver as well to bind the reset driver with the
lookup table.

6737771600 rockchip: rk3588: Add support for sdmmc clocks in SPL
Booting from sdmmc on RK3588 currently works because of a workaround in
the device tree, clocks are reordered so that the driver use ciu-sample
instead of ciu, and the BootRom initializes sdmmc clocks before SPL is
loaded into DRAM.

The sdmmc clocks are normally controlled by TF-A using SCMI. However,
there is a need to control these clocks in SPL, before TF-A has started.

This adds a rk3588_scru driver to control the sdmmc clocks in SPL before
TF-A has started, using scru regs. It also adds a small glue driver to
bind the scmi clock node to the rk3588_scru driver in SPL.

bde73b14f0 rockchip: sdram: add basic support for sdram reg info version 3
Newer DRAM initialization blobs from vendor can encode sdram info in a
new version 3 format. The new format makes use of more bits in sys_reg3
compared to the version 2 format.

Add basic support for detecting the version 3 format and decoding the
high bits used for ddrtype.

This fixes decode of sdram size on my RK3568 boards that have LPDDR4X.

Details on the new format was deciphered from vendor u-boot commit [1].

730a402450 rockchip: rk3066: add clock driver for rk3066 soc
Add the clock driver for the rk3066 platform.

Derived from the rk3288 and rk3188 driver it
supports only a bare minimum to bring up the system
to reduce the TPL size for:
  SDRAM clock configuration.
  The boot devices NAND, EMMC, SDMMC, SPI.
  A UART for the debug messages (fixed) at 115200n8.
  A SARADC for the recovery button.
  A TIMER for the delays (fixed).

There's support for two possible frequencies,
the safe 600MHz which will work with default pmic settings and
will be set to get away from the 24MHz default and
the maximum of 1.416Ghz, which boards can set if they
were able to get pmic support for it.

After the clock tree is set during the TPL probe
there's no parent update support.

In OF_REAL mode the drivers ns16550.c and dw-apb-timer.c
obtain the (fixed) clk_get_rate from the clock driver
instead of platdata.

The rk3066 cru node has a number of assigned-clocks properties
that call the .set_rate() function. Add them to the list so that
they return a 0 instead of -ENOENT.

A possible solution would be to make sure that the rk3288.dtsi and

to find the kind of endpoint by comparing the endpoint compatible value.

This patch is implementing the more flexible second solution.

reset cause is a generic functionality based on the soc
cru registers in rockchip. This can be used for printing
the cause of reset in cpuinfo or some other place where
reset cause is needed. 

Other than cpuinfo, reset cause can also be using during
bootcount for checking the specific reset cause and glow
the led based on the reset cause.

So, let's separate the reset cause code from cpuinfo, and
add a check to build it for rk3399, rk3288 since these two
soc are supporting reset cause as of now.

c3dc39a2f8 arm: Don't include common.h in header files
It is bad practice to include common.h in other header files since it can
bring in any number of superfluous definitions. It implies that some C
files don't include it and thus may be missing CONFIG options that are set
up by that file. The C files should include these themselves.

Update some header files in arch/arm to drop this.

e67243f1a3 video: rockchip: Fix vop modes for rk3399
VOP display endpoint pipeline configuration differs
between rk3288 vs rk3399.

These VOP pipeline configuration depends on how the
different display interfaces connected in sequence to
IN and OUT ports like for,

RK3288:

vopb_out: port {
	#address-cells = <1>;
	#size-cells = <0>;
	vopb_out_edp: endpoint@0 {
		reg = <0>;
		remote-endpoint = <&edp_in_vopb>;
	};
	vopb_out_hdmi: endpoint@1 {
		reg = <1>;
                remote-endpoint = <&hdmi_in_vopb>;
        };
        vopb_out_lvds: endpoint@2 {
                reg = <2>;
                remote-endpoint = <&lvds_in_vopb>;
        };
        vopb_out_mipi: endpoint@3 {
                reg = <3>;
                remote-endpoint = <&mipi_in_vopb>;
        };
};

RK3399:

vopb_out: port {
         #address-cells = <1>;
         #size-cells = <0>;
         vopb_out_edp: endpoint@0 {
                reg = <0>;
                remote-endpoint = <&edp_in_vopb>;
         };
         vopb_out_mipi: endpoint@1 {
                reg = <1>;
                remote-endpoint = <&mipi_in_vopb>;
         };
         vopb_out_hdmi: endpoint@2 {
                reg = <2>;
                remote-endpoint = <&hdmi_in_vopb>;
         };
         vopb_out_mipi1: endpoint@3 {
                reg = <3>;
                remote-endpoint = <&mipi1_in_vopb>;
         };
         vopb_out_dp: endpoint@4 {
                reg = <4>;
                remote-endpoint = <&dp_in_vopb>;
         };
};

here, HDMI interface has endpoint 1 in rk3288 and 2 in rk3399.

The rockchip vop driver often depends on this determined endpoint
number and stored in vop_mode. So based on this vop_mode the bpp
and pin polarity would configure on detected display interface.

Since, the existing driver using rk3288 vop mode settings enabling
the same will result wrong display interface configuration for rk3399.

Add the patch for fixing these vop modes for rk3399.

ee6321fa14 rockchip: Add common reset cause
Add cpu reset cause in common cpu-info file.

This would help to print the reset cause for
various resets.

Right now it support rk3288, rk3399. rest of rockchip
platforms doesn't have reset cause support ye but this
code is more feasible to extend the same.

b52a199e32 arm: rockchip: Add common cru.h
Few of the rockchip family SoC atleast rk3288,
rk3399 are sharing some cru register bits so
adding common code between these SoC families
would require to include both cru include files
that indeed resulting function declarations error.

So, create a common cru include as cru.h then
include the rk3399 arch cru include file and move
the common cru register bit definitions into it.

The rest of rockchip cru files will add it in future.

4ee6d51c5a pwm: rk_pwm: Make PWM driver to support all Rockchip Socs
This PWM driver can be used to support pwm functions
for on all Rockchip Socs.

The previous chips than RK3288 did not support polarity,
and register layout was different from the RK3288 PWM.

The RK3288 keep the current functions.

RK3328 and the chips after it, which can support hardware lock,
configure duty, period and polarity at next same period, to
prevent the intermediate temporary state.

c541bfda2f rockchip: px30: Add support for using UART3 as debug UART
Some generic PX30 SoMs found in the wild use UART3 as their debug output
instead of UART2 (used for MMC) and UART5.

Make it possible to use UART3 as early debug output, with the associated
clock and pinmux configuration. Two sets of output pins are supported (M0/M1).

Future users should also note that the pinmux default in the dts is to use
the M1 pins while the Kconfig option takes M0 as a default.
