From 512feb4e19a262ea0dfd7209506a998897feaadc Mon Sep 17 00:00:00 2001 From: Xiubo Li Date: Fri, 15 Jan 2016 19:35:24 +0800 Subject: [PATCH 01/18] ASoC: fsl_sai: Use usleep_range() instead of msleep() Since msleep() will sleep longer than intended time for values less than 20ms, this patch allows the use of usleep_range for just 1ms. usleep_range is a finer precision implementation of msleep and is designed to be a drop-in replacement for udelay where a precise sleep/busy-wait is unnecessary.

This includes the system controllers on these systems which are controlled via syscon which uses the regmap API which used readl() and writel() to interact with the hardware, meaning that all writes are converted to little endian when writing to the hardware. This caused a bad interaction with the regmap core in big endian mode since it was not aware of the byte swapping and so ended up performing little endian writes. Unfortunately when this issue was noticed it was addressed by updating the DT for the affected devices to specify them as little endian. This happened to work since it resulted in two endianness swaps which cancelled each other out and gave little endian behaviour but meant that the DT was clearly not accurately describing the hardware. The intention of commit 29bb45f25ff305 (regmap-mmio: Use native endianness for read/write) was to fix this by making regmap default to native endianness but this breaks most other MMIO users where the hardware has a fixed endianness and the implementation uses the __raw accessors which are not intended to be used outside of architecture code. Instead use the newly added native-endian DT property to say exactly what we want for these systems.

This is not safe as these interact poorly with spinlocks and are not guaranteed to generate emulated instructions on at least ARM where regmap is commonly used. The APIs that are provided all provide some byte swapping so this is difficult to do with the current regmap-mmio implementation which attempts to use the regmap core byte swapping. We can fix this by modernising the MMIO implementation to use reg_read() and reg_write() operations which were added after the API was implemented and pass simple unsigned integers through to the bus, making use of the formatting provided by the I/O accessors using a similar pattern to that used by the core. This will be less efficient for block I/O operations since we now enable and disable any required clocks per register but it is not clear that any users of regmap-mmio actually use block I/O and there is room to optimise later. This removes support for big endian I/O on 64 bit registers since no I/O accessors are provided, no current users were found and support can be added easily once they are available. In addition make the default endianness little endian. This was the behaviour prior to 29bb45f25ff305 (regmap-mmio: Use native endianness for read/write) and is the behaviour desired by most existing users, the users have been audited and those that need native endianness converted to request it explicitly. Previously native was documented as the default but due to the byte swapping in the accessors this was not correctly implemented.

Szmigiero" Date: Mon, 18 Jan 2016 20:07:44 +0100 Subject: [PATCH 14/18] ASoC: fsl_ssi: remove explicit register defaults There is no guarantee that on fsl_ssi module load SSI registers will have their power-on-reset values. In fact, if the driver is reloaded the values in registers will be whatever they were set to previously. However, the cache needs to be fully populated at probe time to avoid non-atomic allocations during register access. Special case here is imx21-class SSI, since according to datasheet it don't have SACC{ST,EN,DIS} regs. This fixes hard lockup on fsl_ssi module reload, at least in AC'97 mode.
