gpiolib-cdev is extended to support hardware clock type, this patch reflects that fact. Signed-off-by: Dipen Patel Reviewed-by: Linus Walleij Signed-off-by: Thierry Reding

kbuild: replace $(if A,A,B) with $(or A,B)

2022-02-15T03:25:56Z

$(or ...) is available since GNU Make 3.81, and useful to shorten the code in some places. Covert as follows: $(if A,A,B) --> $(or A,B) This patch also converts: $(if A, A, B) --> $(or A, B) Strictly speaking, the latter is not an equivalent conversion because GNU Make keeps spaces after commas; if A is not empty, $(if A, A, B) expands to " A", while $(or A, B) expands to "A". Anyway, preceding spaces are not significant in the code hunks I touched. Signed-off-by: Masahiro Yamada Reviewed-by: Nicolas Schier

tools: gpio-utils: fix various kernel-doc warnings

Fix several problems in kernel-doc notation in gpio-utils.c. gpio-utils.c:37: warning: Incorrect use of kernel-doc format: * gpiotools_request_line() - request gpio lines in a gpiochip gpio-utils.c:61: warning: expecting prototype for doc().

tools: gpio: remove uAPI v1 code no longer used by selftests

2021-02-15T10:43:28Z

gpio-mockup-chardev helper has been obsoleted and removed, so also remove the tools/gpio code that it, and nothing else, was using. Signed-off-by: Kent Gibson Acked-by: Linus Walleij Signed-off-by: Bartosz Golaszewski

tools: gpio: fix %llu warning in gpio-watch.c
