bcd4d4eb2b SPDX-License-Identifier: fixing some problematic GPL-2.0 files
Unlike the other patches in this series so far, this commit fixes a
ambiguity in the license terms for some OMAP files:  the code was
originally derived from the Linux kernel sources, where it was clearly
marked as GPL-2.0 (i. e. without the "or later" part), but the U-Boot
version had a GPL-2.0+ file header added, apparently without
permission / relicensing from the original authors of the code.

Insert a GPL-2.0 SPDX-License-Identifier to fix this.

a704a6d615 ARM: omap3: Implement dpll5 (HSUSB clk) workaround for OMAP36xx/AM/DM37xx according to errata sprz318e.
In chapter 'Advisory 2.1 USB Host Clock Drift Causes USB Spec Non-compliance in Certain Configurations' of the TI Errata it is recommended to use certain div/mult values for the DPLL5 clock setup.
So far u-boot used the old 34xx values, so I added the errata recommended values specificly for 36xx init only.
Also, the FSEL registers exist no longer, so removed them from init.

Tested this on a AM3703 board with 19.2MHz oscillator, which previously couldnt lock the dpll5 (kernel complained). As a consequence the EHCI USB port wasnt usable in U-Boot and kernel. With this patch, kernel panics disappear and USB working fine in u-boot and kernel.

87bd05d78f ARM: OMAP: GPIO: Fix valid range and enable usage of all GPIOs on OMAP5
The omap_gpio driver is used by AM33XX, OMAP3/4, OMAP54XX and DRA7XX SoCs.
These SoCs have different gpio count but currently omap_gpio driver uses hard
coded 192 which is wrong.

This patch fixes this issue by:
1. Move define of OMAP_MAX_GPIO to all arch/arm/include/asm/arch-omap*/gpio.h.
2. Update gpio bank settings and enable GPIO modules 7 & 8 clocks for OMAP5.

Thanks for Lubomir Popov to provide valuable comments to fix this issue.

4d0df9c1e9 OMAP3+: introduce generic ABB support
Adaptive Body Biasing (ABB) modulates transistor bias voltages
dynamically in order to optimize switching speed versus leakage.
Adaptive Body-Bias ldos are present for some voltage domains
starting with OMAP3630. There are three modes of operation:

* Bypass - the default, it just follows the vdd voltage
* Foward Body-Bias - applies voltage bias to increase transistor
  performance at the cost of power.  Used to operate safely at high
  OPPs.
* Reverse Body-Bias - applies voltage bias to decrease leakage and
  save power.  Used to save power at lower OPPs.

c3d2c24f6c OMAP3/4/5/AM33xx: Correct logic for checking FAT or RAW MMC
In the case of booting from certain peripherals, such as UART, we must
not see what the device descriptor says for RAW or FAT mode because in
addition to being nonsensical, it leads to a hang.  This is why we have
a test currently for the boot mode being within range.  The problem
however is that on some platforms we get MMC2_2 as the boot mode and not
the defined value for MMC2, and in others we get the value for MMC2_2.
This is required to fix eMMC booting on omap5_uevm.

Tested on am335x_evm (UART, NAND, SD), omap3_beagle (NAND, SD on
classic, SD only on xM rev C5) and omap5_uevm (SD, eMMC).

bcc6cc9b37 omap3: allow dynamic selection of gfx_format
Currently, omap3_dss_panel_config() sets gfx_format to a value that is hardcoded
in the code. This forces anyone who wants to use a different gfx_format to make
adjustments after calling omap3_dss_panel_config(). This could be avoided if the
value of gfx_format were parameterized as input for omap3_dss_panel_config().

Make gfx_format a field in struct panel_config, and update existing structs to
set this field to the value that was originally hard coded.

a7778f8fbe omap_hsmmc: Wait for CMDI to be clear
Before we can send a command we need both the DATI (command inhibit on
mmc_dat line) bit and CMDI (command inhibit on mmc_cmd line) are clear.
The previous behavior of only checking on DATI was insufficient on some
cards and incorrect behavior in any case.  This makes the code check
for both bits being clear and makes the error print more clear as
to what happened.  DATI_CMDDIS is removed as it was unused elsewhere
in the code and stood for 'DATI is set, cmds are disabled still'.

f4dac3e16c omap3:clock: configure GFX clock to 200MHz for AM/DM37x
AM/DM37x is another OMAP3 variant, where the GFX clock has been
boosted to 192MHz/200MHz. So fix the GFX_DIV value for this change.

HW Errata: Due to dependency of TV out clock of 54MHz, it is not
possible to configure GFX to 192MHz. So as per HW errats, the
recommended GFX clock is 200MHz (=CORE_CLK/2).
