Subject: arm: lpc32xx: remove direct control of GPIOs from shared mach file
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=0ac1a101f5dd28c3894be3c0230ee7ea2e05e8aa;p=GitHub%2Fmoto-9609%2Fandroid_kernel_motorola_exynos9610.git

arm: lpc32xx: remove direct control of GPIOs from shared mach file

The change removes GPIO configuration and control of LCD, backlight
and SD voltage regulators from the shared among all LPC32xx boards
mach file, Phytec PHY3250 board should have the description of these
regulators in its DTS file.
