The 4.3 kernel release has been released just a few days ago. For details about the big new features in this release, we as usual recommend to read LWN.net articles covering the merge window: part 1, part 2 and part 3.
According to the KPS statistics, there were 12128 commits in this release, and with 110 patches, Bootlin is the 20th contributing company. As usual, we did some contributions to this release, though a somewhat smaller number than for previous releases.
Our main contributions this time around:
- On the support for Atmel ARM SoCs
- Alexandre Belloni contributed a fairly significant number of cleanups: description of the slow clock in the Device Tree, removal of left-over from platform-data usage in device drivers (no longer needed now that all Atmel ARM platforms use the Device Tree).
- Boris Brezillon contributed numerous improvements to the
atmel-hlcdc, which is the DRM/KMS driver for the modern Atmel ARM SoCs. He added support for several SoCs to the driver (SAMA5D2, SAMA5D4, SAM9x5 and SAM9n12), added PRIME support, and support for the RGB565 and RGB444 output configurations. - Maxime Ripard improved the dmaengine drivers for Atmel ARM SoCs (
at_hdmacandat_xdmac) to add memset and scatter-gather memset capabilities.
- On the support for Allwinner ARM SoCs
- Maxime Ripard converted the SID driver to the newly introduced nvmem framework. Maxime also did some minor pin-muxing and clock related updates.
- Boris Brezillon fixed some issues in the NAND controller driver.
- On the support for Marvell EBU ARM SoCs
- Thomas Petazzoni added the initial support for suspend to RAM on Armada 38x platforms. The support is not fully enabled yet due to remaining stability issues, but most of the code is in place. Thomas also did some minor updates/fixes to the XOR and crypto drivers.
- Grégory Clement added the initial support for standby, a mode that allows to forcefully put the CPUs in deep-idle mode. For now, it is not different from what cpuidle provides, but in the future, we will progressively enable this mode to shutdown PHY and SERDES lanes to save more power.
- On the RTC subsystem, Alexandre Belloni did numerous fixes and cleanups to the
rx8025driver, and also a few to theat91sam9andat91rm9200drivers. - On the common clock framework, Boris Brezillon contributed a change to the
->determinate_rate()operation to fix overflow issues. - On the PWM subsystem, Boris Brezillon contributed a number of small improvements/cleanups to the subsystem and some drivers: addition of a
pwm_is_enabled()helper, migrate drivers to use the existing helper functions when possible, etc.
