2019-08-27clocksource/drivers/npcm: Fix GENMASK and timer operationAvi Fishman
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.
