[PATCH v7 00/13] Add Broadcom VK driver
From: Scott Branden
Date: Tue Nov 17 2020 - 18:24:48 EST
This patch series drops previous patches in [1]
that were incorporated by Kees Cook into patch series
"Introduce partial kernel_read_file() support" [2].
Remaining patches are contained in this series to add Broadcom VK driver.
(which depends on request_firmware_into_buf API addition which has
now been accepted into the upstream kernel as of v5.10-rc1).

Changes from v6:
- drop QSTATS patch as it needs to be reviewed if trace_printk makes sense
- add wdog and IPC interface alerts
- add boundary check to msgq and peerlog
- clear additional registers on reset
Changes from v5:
- dropped sysfs patch from series for now as rework to use hwmon
- tty patch still at end of series to drop if another solution available
- updated cover letter commit to point to Kees' latest patch submission in [2]
- specified --base with Kees' patches applied (kernel branches don't have these yet)
- removed trivial comment
- moved location of const to before the struct in two declarations
- changed dev_info to dev_warn and only print when irq don't match expected
- changed dev_info to dev_dbg when printing debug QSTATS
- removed unnecessary %p print
Changes from v4:
- fixed memory leak in probe function on failure
- changed -1 to -EBUSY in bcm_vk_tty return code
- move bcm_vk_tty patch to end of patch series so it
can be dropped from current patch series if needed
and rearchitected if needed.
Changes from v3:
- split driver into more incremental commits for acceptance/review
- lowered some dev_info to dev_dbg
- remove ANSI stdint types and replace with linux u8, etc types
- changed an EIO return to EPFNOSUPPORT
- move vk_msg_cmd internal to driver to not expose to UAPI at this time
Changes from v2:
- open code BIT macro in uapi header
- A0/B0 boot improvements
Changes from v1:
- declare bcm_vk_intf_ver_chk as static
