Re: [PATCH] ASoC: rockchip: Fix incorrect VDW value for 24 bit

Hi,

å 2015å11æ25æ 16:54, Sjoerd Simons åé:
Correct valid data word register value for 24 bit data width. The
bit value should be 10 (aka 0x2), not 0x10.

This fixes playback of 24 bit audio.

Yep,
From the TRM says: (RK3288/RK3368...)

VDW
Valid data width
00: 16bit
01: 20bit
10: 24bit
11: reserved
....

So feel free add my tag:
