From e4d0db60e8d25cc62b9b7e32c18e7f6acc136055 Mon Sep 17 00:00:00 2001 From: John Hsu Date: Tue, 7 Nov 2017 15:23:17 +0800 Subject: ASoC: nau8540: reset state machine for channel phase sync The four channel ADCs in NAU85L40 have difference control registers, it is hard to synchronous these four channels without correct sequence. The phase difference will not be a constant and not to conjecture easily. It may be 2.55 degree, or more ,or less. Intended to prevent phase difference of channels, the solution as follows: (1)Channel_Sync need to be enabled. (2)Do soft reset without affecting register when recording done.

The comments show as follows: (1)ICTRL_LATCH: FLL DSP speed capability control When FLL running at high frequency with long decimal number, DSP needs to operate at high speed. FLL DSP can optimize between performance and power consumption by ICTRL_LATCH.(111 has highest power consumption.) The default setting can be used to reduce power. (2)CUTOFF500: loop filter cutoff frequency at 500Khz It will give the best FLL performance but highest power consumption to enable the cutoff frequency. FLL Loop Filter enable to reduce FLL output noise, especially,(DCO frequency)/(FLL input reference frequency) is not a integer. (3)GAIN_ERR: FLL gain error correction threshold setting The threshold is comparison between DCO and target frequency. The value 1111 has the most sensitive threshold, that is, 1111 can have the most accurate DCO to target frequency. However, the gain error setting conditionally and inversely depends on FLL input reference clock rate. Higher FLL reference input frequency can only set lower gain error, such as 0000 for input reference from MCLK=12.288Mhz. On the other side, if FLL reference input is from Frame Sync, 48KHz, higher error gain can apply such as 1111.

The driver add more protections to make it stronger. The improvements as follows: (1)Give backup table the default value. The values are the same with the default of hardware registers. The impact will decline once restoring the backup table in the wrong way. (2)Add xtalk_baktab_initialized flag. The flag can keep the initiation status of backup table. It helps to backup and restore the backup-table correctly. (3)Add cancel parameter in the restore function. The volume ramping should do in crosstalk DONE state only. Otherwise, the delay action is not allowed because the restore may happen during the jack eject interruption. (4)Add xtalk_protect condition check before scheduling work in ISR. It makes sure the semaphore hold during the crosstalk measurement. The sequence is still under protection from playback interference.
