[PATCH v4 2/2] clk: mediatek: Add drivers for MediaTek MT6735 main clock and reset drivers
Yassine Oudjana
yassine.oudjana at gmail.com
Wed Jun 26 13:24:05 PDT 2024
From: Yassine Oudjana <y.oudjana at protonmail.com>
Add drivers for MT6735 apmixedsys, topckgen, infracfg and pericfg
clock and reset controllers. These provide the base clocks and resets
on the platform, enough to bring up all essential blocks including
PWRAP, MSDC and peripherals (UART, I2C, SPI).
