This function currently assumes that the control FDT is used. Update it
to allow a root node to be passed, so it can work with any tree.
Also add a comment to ofnode_get_by_phandle() so that its purpose is

The udelay() function in lib/time.c contains a WATCHDOG_RESET()
call. So use __udelay() in max6370_wdt.c to prevent recursion.

The udelay() function in lib/time.c contains a WATCHDOG_RESET()
call. The only reason this doesn't lead to a catastrophic infinite
recursion is due to the rate-limiting in wdt-uclass.c:
if (time_after_eq(now, priv->next_reset)) {
priv->next_reset = now + priv->reset_period;
wdt_reset(dev);
}
But this would fall apart if ->next_reset was updated after calling the
device's reset method.
This is needlessly fragile, and it's easy enough to avoid that
recursion in the first place by just using __udelay() directly.

Xilinx changes for v2023.01-rc1 (round 2)
xilinx:
- Add support for new Versal NET SOC
zynqmp:
- Use mdio bus for ethernet phy description
- Wire ethernet phy reset via i2c-gpio
versal:
- Config cleanup
Currently all GPIOs supported by CMD_EXT_CONTROL/CMD_GET_EXT_CONTROL_STATUS
commands (last 16 GPIOs) are available only when FEAT_PERIPH_MCU feature
bit is set. So do not register these GPIOs by U-Boot driver when this
feature bit is not set, so U-Boot 'gpio' command would see only GPIOs which
really exists.

U-Boot core code already handles the case when RAM size is bigger than
CONFIG_MAX_MEM_MAPPED. So there is no need to do duplicate check in fsl ddr
driver for CONFIG_MAX_MEM_MAPPED. Instead simplify code to just check if
RAM size can be representable in phys_size_t type. And avoid printing
warning if phys_size_t is just 1 byte smaller than RAM size, which is the
typical situation with 4 GB DDR module.
Signed-off-by: Pali Rohár <pali@kernel.org>
Function fsl_ddr_compute() always return size in unsigned long long type,
but function fsl_ddr_sdram_size() returns size in phys_size_t type.
When 36-bit addressing mode is not enabled then phys_size_t type is only
32-bit and thus it cannot store value 4GB (0x100000000). Function
fsl_ddr_sdram_size() in this case returns truncated value 0x0.
Fix this issue by returning the highest representable value, which is
0xffffffff (4GB - 1 byte).
This change fixes crashing of proper U-Boot because it detected 4 GB module
as RAM with zero size.

Check needs to be done against CONFIG_MAX_MEM_MAPPED macro and not fixed

only for non-SPL builds, during init_dram() call.

The mtk clock framework in u-boot uses array index for searching clock
parent (kernel uses strings for search), so we need to specify a special
clock with ID=0 for CLK_XTAL in u-boot.
In the mt7622/mt7629 clock tree, the clocks with ID=0 never call
mtk_topckgen_get_mux_rate, adn return xtal clock directly. This what we
expected.
However for newer chips, they may have some clocks with ID=0 not
representing the xtal clock and still needs mtk_topckgen_get_mux_rate be
called. Current logic will make entire clock driver not working.
This patch adds a flag to indicate that whether a clock driver needs clocks
with ID=0 to call mtk_topckgen_get_mux_rate.
