Avi Fishman a2b58537b4 clocksource/drivers/npcm: Fix GENMASK and timer operation
NPCM7XX_Tx_OPER GENMASK bits are wrong, fix them.

Hopefully the NPCM7XX_REG_TICR0 register reset value of those bits was 0,
so it did not cause an issue.

The function npcm7xx_timer_oneshot() reads the register
NPCM7XX_REG_TCSR0, modifies it and then reads it again overwriting the
previous changes. Remove the extra read which is pointless.

The function npcm7xx_timer_periodic() is correct but the code writes
to the NPCM7XX_REG_TICR0 register while it is dealing with the
NPCM7XX_REG_TCSR0 register, that is confusing. Separate the write to
the registers in the code for the sake of clarity.

Tomer Maimon 1c00289ecd clocksource/drivers/npcm: Add NPCM7xx timer driver
Add Nuvoton BMC NPCM7xx timer driver.

The clocksource Enable 24-bit TIMER0 and TIMER1 counters,
while TIMER0 serve as clockevent and TIMER1 serve as clocksource.
