X-Git-Tag: v2024.07-rc1~87^2~15
X-Git-Url: http://git.openpandora.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=493f069062b90e7aba3612651a064f2f313cfc68;p=pandora-u-boot.git

pinctrl: qcom: pass pin number to get_function_mux callback

This patch is the preparation for SM8150 support. This new SoC
depending on the particular pin can have different numbers for the
same function. For example "rgmii" function for GPIO4 has id=2 while
for GPIO59 it has id=1. So, to support this type of SoCs,
get_function_mux() callback needs to know for which pin the function
is requested.
