[PATCH v2 29/41] ARM: s3c24xx: move s3cmci pinctrl handling into board files

From: Krzysztof Kozlowski
Date: Thu Aug 06 2020 - 14:37:13 EST

From: Arnd Bergmann <arnd@xxxxxxxx>

Rather than call the internal s3c_gpio_cfgall_range() function
through a platform header, move the code into the set_power
callback that is already exported by the board, and add
a default implementation.

In DT mode, the code already does not set the pin config,
so nothing changes there.

[krzk: Rebase and correct set_power in mach-h1940.c]
Signed-off-by: Krzysztof Kozlowski <krzk@xxxxxxxxxx>

---

Changes since v1:
1. Minor whitespace changes,
2. mach-h1940.c already had set_power.
