Subject: [PATCH v4 3/4] clk: mediatek: Add pcw_chg_shift control
From: Sam Shih <sam.shih@...iatek.com>
Introduce pcw_chg_shfit control to replace hardcoded PCW_CHG_MASK macro.
This will needed for clocks on the MT7988 SoC.

Signed-off-by: Daniel Golle <daniel@...rotopia.org>

v4: always set .pcw_chg_shift if .pcw_chg_reg is used instead of
having an if-expression in mtk_pll_set_rate_regs().
v3: use git --from ...
v2: no changes
