After the recent corrections to the R-Car gen2/3 LVDS startup code, already similar enough at their ends rcar_lvds_enable_gen{2|3}() started asking for a merge and it's becoming actually necessary with the addition of the R-Car V3M (R8A77970) support -- this gen3 SoC has gen2-like LVDPLLCR layout.

The LVDCR1 register for the R-Car gen3 SoCs was documented as having the layout different from the gen2 SoCs in the early R-Car gen3 manuals but since v0.52 the LVDCR1 layout is described as being the same as on the gen2 SoCs; the old CHn control values are said to be prohibited now (and there seems to be no valid output signal when they are used).

In general, PLL has VCO (= Voltage controlled oscillator), one of the very important electronic feature called as "jitter" is related to this VCO. In academic generalism, VCO should be maximum to be more small jitter. In high frequency clock, jitter will be large impact. Thus, selecting Hi VCO is general theory. fin fvco fout fclkout in --> [1/M] --> |PD| -> [LPF] -> [VCO] -> [1/P] -+-> [1/FDPLL] -> out +-> | | | | | +-----------------[1/N]<-------------+ fclkout = fvco / P / FDPLL -- (1) In PD, it will loop until fin/M = fvco/P/N fvco = fin * P * N / M -- (2) (1) + (2) indicates fclkout = fin * N / M / FDPLL In this device, N = (n + 1), M = (m + 1), P = 2, FDPLL = (fdpll + 1). fclkout = fin * (n + 1) / (m + 1) / (fdpll + 1) This is the datasheet formula. One note here is that it should be 2kHz < fvco < 4096MHz To be smaller jitter, fvco should be maximum, in other words, N as large as possible, M as small as possible driver should select. Here, basically M=1. This patch do it. Reported-by:HIROSHI INOSE <hiroshi.inose.rb@renesas.com> Signed-off-by:

except, again, POLLFREE and POLL_BUSY_LOOP. With this, we finally get to the promised end result: - POLL{IN,OUT,...} are plain integers and *not* in __poll_t, so any stray instances of ->poll() still using those will be caught by sparse. - eventpoll.c and select.c warning-free wrt __poll_t - no more kernel-side definitions of POLL... - userland ones are visible through the entire kernel (and used pretty much only for mangle/demangle) - same behavior as after the first series (i.e. sparc et.al. epoll(2) working correctly).

This is the mindless scripted replacement of kernel use of POLL* variables as described by Al, done by this script: for V in IN OUT PRI ERR RDNORM RDBAND WRNORM WRBAND HUP RDHUP NVAL MSG; do L=`git grep -l -w POLL$V | grep -v '^t' | grep -v /um/ | grep -v '^sa' | grep -v '/poll.h$'|grep -v '^D'` for f in $L; do sed -i "-es/^\([^\"]*\)\(\<POLL$V\>\)/\\1E\\2/" $f; done done with de-mangling cleanups yet to come. NOTE! On almost all architectures, the EPOLL* constants have the same values as the POLL* constants do. But they keyword here is "almost". For various bad reasons they aren't the same, and epoll() doesn't actually work quite correctly in some cases due to this on Sparc et al. The next patch from Al will sort out the final differences, and we should be all done. Scripted-by: -

After the preparations (in this series) switch to returning EPOLL... from ->poll() instances is completely mechanical and kernel-side POLL... can go away. The last step (killing kernel-side POLL... and unifying {de,}mangle_poll() has to be done after the search-and-replace job, since we need userland-side POLL... for unified {de,}mangle_poll(), thus the cherry-pick at the last step.

Expose new ioctls to create/destroy a performance monitor object and query the counter values of this perfmance monitor. Note that a perfomance monitor is given an ID that is only valid on the file descriptor it has been allocated from. A performance monitor can be attached to a CL submission and the driver will enable HW counters for this request and update the performance monitor values at the end of the job. Signed-off-by:

59f47eff ("powerpc/pci: Use of_irq_parse_and_map_pci() helper") replaced of_irq_parse_pci() + irq_create_of_mapping() with of_irq_parse_and_map_pci(), but neglected to capture the virq returned by irq_create_of_mapping(), so virq remained zero, which caused INTx configuration to fail. Save the virq value returned by of_irq_parse_and_map_pci() and correct the virq declaration to match the of_irq_parse_and_map_pci() signature.

This function returns realloc'ed memory, so the returned pointer must be passed to free() when done. So, 'const' qualifier is odd. It is allowed to modify the expanded string. Signed-off-by:Masahiro Yamada <yamada.masahiro@socionext.com>
