pinctrl: use devm_platform_ioremap_resource() to simplify code

2019-11-05T14:33:40Z

devm_platform_ioremap_resource() internally have platform_get_resource() and devm_ioremap_resource() in it. So instead of calling them separately use devm_platform_ioremap_resource() directly.

pinctrl: xway: fix gpio-hog related boot issues

2018-12-17T22:11:18Z

This patch is based on commit a86caa9ba5d7 ("pinctrl: msm: fix gpio-hog related boot issues"). It fixes the issue that the gpio ranges needs to be defined before gpiochip_add(). Therefore, we also have to swap the order of registering the pinctrl driver and registering the gpio chip. You also have to add the "gpio-ranges" property to the pinctrl device node to get it finally working. Signed-off-by: Martin Schiller Acked-by: John Crispin Signed-off-by: Linus Walleij

treewide: devm_kzalloc() -> devm_kcalloc()

2018-06-12T23:19:22Z

The devm_kzalloc() function has a 2-factor argument form, devm_kcalloc(). This patch replaces cases of: devm_kzalloc(handle, a * b, gfp) with: devm_kcalloc(handle, a * b, gfp) as well as handling cases of: devm_kzalloc(handle, a * b * c, gfp) with: devm_kzalloc(handle, array3_size(a, b, c), gfp) as it's slightly less ugly than: devm_kcalloc(handle, array_size(a, b), c, gfp) This does, however, attempt to ignore constant size factors like: devm_kzalloc(handle, 4 * 1024, gfp) though any constants defined via macros get caught up in the conversion. Any factors with a sizeof() of "unsigned char", "char", and "u8" were dropped, since they're redundant. Some manual whitespace fixes were needed in this patch, as Coccinelle really liked to write "=devm_kcalloc..." instead of "= devm_kcalloc...". The Coccinelle script used for this was: // Fix redundant parens around sizeof(). @@ expression HANDLE; type TYPE; expression THING, E; @@ ( devm_kzalloc(HANDLE, - (sizeof(TYPE)) * E + sizeof(TYPE) * E , ...) | devm_kzalloc(HANDLE, - (sizeof(THING)) * E + sizeof(THING) * E , ...) ) // Drop single-byte sizes and redundant parens. @@ expression HANDLE;
