Pull documentation updates from Jonathan Corbet: "It's a somewhat calmer cycle for docs this time, as the churn of the mass RST conversion is happily mostly behind us. - A new document on reproducible builds. - We finally got around to zapping the documentation for hardware support that was removed in 2004; one doesn't want to rush these things. - The usual assortment of fixes, typo corrections, etc" * tag 'docs-5.4' of git://git.lwn.net/linux: (67 commits) Documentation: kbuild: Add document about reproducible builds docs: printk-formats: Stop encouraging use of unnecessary %h[xudi] and %hh[xudi] Documentation: Add "earlycon=sbi" to the admin guide doc:lock: remove reference to clever use of read-write lock devices.txt: improve entry for comedi (char major 98) docs: mtd: Update spi nor reference driver doc: arm64: fix grammar dtb placed in no attributes region Documentation: sysrq: don't recommend 'S' 'U' before 'B' mailmap: Update email address for Quentin Perret docs: ftrace: clarify when tracing is disabled by the trace file docs: process: fix broken link Documentation/arm/samsung-s3c24xx: Remove stray U+FEFF character to fix title Documentation/arm/sa1100/assabet: Fix 'make assabet_defconfig' command Documentation/arm/sa1100: Remove some obsolete documentation docs/zh_CN: update Chinese howto.rst for latexdocs making Documentation: virt: Fix broken reference to virt tree's index docs: Fix typo on pull requests guide kernel-doc: Allow anonymous enum Documentation: sphinx: Don't parse socket() as identifier reference Documentation: sphinx: Add missing comma to list of strings ...

+================================
Two files are introduced:
a) 'arch/mips/include/asm/mach-au1x00/au1xxx_ide.h'

- timing parameters for PIO mode 0/1/2/3/4
- timing parameters for MWDMA 0/1/2

+ - timing parameters for PIO mode 0/1/2/3/4
+ - timing parameters for MWDMA 0/1/2
b) 'drivers/ide/mips/au1xxx-ide.c'
contains the functionality of the AU1XXX IDE driver
Following extra configs variables are introduced:
- CONFIG_BLK_DEV_IDE_AU1XXX_PIO_DBDMA - enable the PIO+DBDMA mode
- CONFIG_BLK_DEV_IDE_AU1XXX_MDMA2_DBDMA - enable the MWDMA mode
+ CONFIG_BLK_DEV_IDE_AU1XXX_PIO_DBDMA
+ - enable the PIO+DBDMA mode
+ CONFIG_BLK_DEV_IDE_AU1XXX_MDMA2_DBDMA

-SUPPORTED IDE MODES
--------------------
+Supported IDE Modes
+===================
The AU1XXX IDE driver supported all PIO modes - PIO mode 0/1/2/3/4 - and all
MWDMA modes - MWDMA 0/1/2 -. There is no support for SWDMA and UDMA mode.
