From 8e56d5b834610504e232641565236ac60740a858 Mon Sep 17 00:00:00 2001 From: Ben Gardiner Date: Tue, 24 May 2011 14:50:16 -0400 Subject: [PATCH] ASoC: davinci-pcm: expand the .formats Based on the data_type test in ping_pong_dma_setup, davinci-pcm is capable of handling data of width up to and including 32bits. " if ((data_type == 0) || (data_type > 4)) { printk(KERN_ERR "%s: data_type=%i\n", __func__, data_type); return -EINVAL; } " Update the .format member of the snd_pcm_hardware instances it registers to reflect this capability.
