This is a rework of Cyrille's patches named: [PATCH v3 0/2] ASoC: add driver for Atmel I2S controller https://lkml.org/lkml/2015/9/29/454
This is the version 5 of the series, and addresses the received feedback on the mailing lists.
This series applies on top of clk-next branch of clk/linux.git.
Based on received feedback, I created a mux clock driver to select the I2S clock source, that also includes proper devicetree bindings and nodes. Also, I added the I2S nodes in sama5d2's devicetree, with the missing pin muxing for the second I2S controller.
Alexandre Belloni plans to change the at91 fine grained clock nodes and he recommended to leave the bindings for this clock driver in the same (wrong) manner, so he could fix them all at once.
This series of patches adds support to the new Atmel I2S controller embedded on sama5d2 SoCs.
ChangeLog
v4 -> v5 - removed patches: [PATCH v4 4/7] ASoC: atmel-i2s: dt-bindings: add DT bindings for I2S controller [PATCH v4 5/7] ASoC: atmel-i2s: add driver for the new Atmel I2S controller from this series since they were applied to the asoc tree at: https://git.kernel.org/pub/scm/linux/kernel/git/broonie/sound.git - addressed comments received on the mux clock;
v3 -> v4 - as suggested by Rob Herring: - added a clock mux driver for I2S's clock control bit; - more precise description of I2S's devicetree bindings; - removed SoC and internal detalls from bindings; - addressed comments from Mark Brown; - added devicetree nodes and pin muxing for I2S;
v2 -> v3 - fix the coding style, add some more comments and add a section dedicated to sama5d2 SoCs in the DT binding documentation as suggested by Mark Brown.
v1 -> v2 - initialize dev->dev before calling dev->caps->mck_init()
