Subject: [PATCH v3 0/2] Add Cadence I2S-MC controller driver
Date: Wed, 8 May 2024 15:04:04 +0800 [thread overview]
Message-ID: <20240508070406.286159-1-xingyu.wu@starfivetech.com> (raw)
The Cadence Multi-channel I2S (I2S-MC) Controller implements a function of
the multi-channel (up to 8-channel) bus. Each stereo channel combines
functions of a transmitter and a receiver, and can switch freely between
them. Each channel has independent gating, clock and interruption control.
It also support some of these channels are used as playback and others can
also be used as record in the same time.
Four I2S controllers are used on the StarFive JH8100 SoC. Two of the I2S
controllers use two stereo channels, one of them use four channels, and
one use eight. It had tested on the fpga with WM8960 and PDM.
Changes since v2:
- Dropped the description of interrupts in bindings.
- Modified the properties like 'compatible' and 'required'.
- Defined the special property in top-level and made it false in other
case in the bindings.
- Added the test of other format in the driver.
- Changed the return values and switch the TX and RX channels for
convenience.
- Modified the macros about 'SND_SOC_DAIFMT_CBM_CFM'.
- Added pm_runtime_set_active() to fix the state of pm_runtime.
v2: https://lore.kernel.org/all/20240320090239.168743-1-xingyu.wu@starfivetech.com/
Changes since v1:
- Added new compatible for StarFive JH8100 SoC and a special property to
be got as the max channels number in the bindings.
- Dropped the useless '|' in the bindings.
- Moved the drivers to a new folder named 'cdns' and modified the name
of functions.
v1: https://lore.kernel.org/all/20231221033223.73201-1-xingyu.wu@starfivetech.com/
