This series adds the PWM driver support for the APWM feature for eCAP on

2. Fix build warning in ti-ehrpwm driver in dev_deb().
3. Enable eCAP0 PWM and LCD pin muxing to support splash screen on
AM335x EVM[2].

dropping the device tree changes in this series due to OF_UPSTREAM
conflict.
As we are dropping the DT patch, started with the new series instead of
V2.
This series doesn't contain defconfig changes since we don't want to
enable LCD, splash screen and PWM support by default.
Enabling splash screen and PWM support in defconfig causes u-boot crash
on AM335x based beaglebone black. This will be handled in a separate
patch.

On AM335x EVM[1],
1. pin AM335X_ECAP0_IN_PWM0_OUT is used to enable the
backlight. ECAP0 can be configured in single channel PWM mode.
If CONFIG_PWM_TI_ECAP is enabled, perform eCAP0 pin muxing.
2. Pins LCD_DATA0 - LCD_DATA15, gpmc_ad8 - gpmc_ad15 and
lcd_vsync, lcd_sync, lcd_ac_bias_en, lcd_pclk are used for driving LCD.
If CONFIG_AM335X_LCD is enabled, perform the LCD pin muxing.
This is required to enable splash screen support on AM335x EVM.

If CONFIG_PWM_TI_EHRPWM is enabled, it throws the build warning in
dev_dbg() due to incorrect format specifier as,
"warning: format ‘%lx’ expects argument of type ‘long unsigned int’, but
argument 4 has type ‘fdt_addr_t’ {aka ‘unsigned int’}".
Fix this with the correct format specifier.

In am33xx SoC[1], enhanced capture (eCAP) supports auxiliary PWM (APWM).
This series adds the PWM driver support for the APWM feature for eCAP on
AM33xx.
eCAP HW also supports the capture mode. Currently, this driver only
supports APWM.
This is based on the Linux kernel driver -> drivers/pwm/pwm-tiecap.c
Version: v6.12
Tested on AM335x EVM[2].

RAM drivers using Device Model currently lack of their own Kconfig menu
entry, which makes Kconfig put all options of the class in the top-level
menu of device drivers. These options are also incorrectly grouped with
pinctrl options in the generated .config, which is hard to read. Let's
create a menu entry for these drivers.

Although if we don't setup an initrd, there could be a stale initrd
setting from the previous boot firmware in the live device tree. So,
make sure there is no setting left if we don't want an initrd.
This can happen when booting on a Raspberry Pi. The boot firmware can
happily load an initrd before us and configuring the addresses in the
live device tree we get handed over.
Especially the setting `auto_initramfs` in config.txt is dangerous.
When enabled (default), the firmware tries to be smart and looks for
initramfs files.

Use lbaint_t for blknr to avoid overflow in ext4fs_read_file().
Background:
blknr (block number) used in ext4fs_read_file() could be increased to a
very large value and causes a wrap around at 32 bit signed integer max,
thus becomes negative. This results in an out-of-normal range for sector
number (during the assignment delayed_start = blknr) where delayed_start
sector is typed uint64 lbaint_t. This causes the "Read outside partition"
error.
Looks like we also have this overflown problem in ext4_write.c that needs
to be addressed.
This patch was tested on the Synology DS116 (Armada 385) board, and a
4TB Seagate HDD.

Quentin Schulz <foss+uboot@0leil.net> says:
Out of all the dev_read_*_default functions, only two do not properly
use the type as argument and return type: dev_read_u32_default and
dev_read_s32_default. They both use int instead of u32/s32.
Considering that it's generally not guaranteed that an int is 4 bytes
but also for consistency sake, let's have them use the expected type.
Note that I have not tested this, just stumbled upon that inconsistency
by chance.

dev_read_s32_default is for getting an s32 from a Device Tree property
and allows to take a default value if that property is missing.
Considering it calls ofnode_read_u32_default which takes a u32 and
returns a u32, it should do the same instead of using an int, especially
considering that int size is typically architecture-specific, as opposed
to s32/u32.
s32 and u32 being the same size, dev_read_s32* functions calling
ofnode_read_u32_default shouldn't be an issue (at the type level at
least) as the information will be stored appropriately in 4B regardless
of the sign.
This incidentally matches all other dev_read_*_default functions.

Add support for configuring DRAM controller on STM32MP13xx SoC.
The DRAM controller is basically identical to the DWC controller
on STM32MP15xx SoC, except the bus width is reduced from 32bit to
16bit and a few registers and bits are therefore not present.
Handle the difference by factoring these parts out. Use IS_ENABLE()
as much as possible to assure code which is not enabled on builds
for a single SoC gets compiled out. Handle the different offset of
RCC_DDRITFCR register and missing DDRC2 clock the same way.

Add SPL support and clock tree init to STM32MP13 RCC driver. This
consists of two parts, make SCMI into an optional dependency and
add clock tree initialization. The SCMI dependency is made optional
first by registering the few core clock provided by SCMI clock as
fixed clock, and second by letting the clock core parse out the
clock configuration from SoC registers. The clock initialization
code is derived from STM32MP15xx clock tree initialization code,
which is almost identical, except for the use of new PLL2000 for
PLL1 on STM32MP13xx .
