2021-07-27clk: mediatek: Add configurable enable control to mtk_pll_dataChun-Jie Chen
In all MediaTek PLL design, bit0 of CON0 register is always the enable bit. However, there's a special case of usbpll on MT8192. The enable bit of usbpll is moved to bit2 of other register. Add configurable en_reg and pll_en_bit for enable control or default 0 where pll data are static variables. Hence, CON0_BASE_EN could also be removed. And there might have another special case on other chips, the enable bit is still on CON0 register but not at bit0.

2021-07-27clk: mediatek: Fix asymmetrical PLL enable and disable controlChun-Jie Chen
In fact, the en_mask is a combination of divider enable mask and pll enable bit(bit0). Before this patch, we enabled both divider mask and bit0 in prepare(), but only cleared the bit0 in unprepare(). In the future, we hope en_mask will only be used as divider enable mask. The enable register(CON0) will be set in 2 steps: first is divider mask, and then bit0 during prepare(), and vice versa. But considering backward compatibility, at this stage we allow en_mask to be a combination or a pure divider enable mask. And then we will make en_mask a pure divider enable mask in another following patch series.

2021-07-27clk: mediatek: Get regmap without syscon compatible checkChun-Jie Chen
Not all clock providers need to be marked compatible with "syscon" for system configuration usage, so use device_node_to_regmap() to skip "syscon" check.

2021-02-09clk: mediatek: mux: Update parent at enable timeLaurent Pinchart
The mux clocks don't always correctly take the new parent into account when the parent is updated while the clock is disabled. Set the update bit when enabling the clock to force an update of the mux.
