2020-03-30pwm: omap-dmtimer: Fix PWM enabling sequenceLokesh Vutla
To configure DM timer in PWM mode the following needs to be set in OMAP_TIMER_CTRL_REG using set_pwm callback: - Set toggle mode on PORTIMERPWM output pin - Set trigger on overflow and match on PORTIMERPWM output pin. - Set auto reload This is a one time configuration and needs to be set before the start of the DM timer. But the current driver tries to set the same configuration for every period/duty cycle update, which is not needed. So move the PWM setup before enabling timer and do not update it in pwm_omap_dmtimer_config().

2020-03-30pwm: omap-dmtimer: Drop unused header fileLokesh Vutla
pwm_omap_dmtimer.h is used only: - to typedef struct omap_dm_timer to pwm_omap_dmtimer - for macro PWM_OMAP_DMTIMER_TRIGGER_OVERFLOW_AND_COMPARE Rest of the file is pretty mush unsed.

2020-03-30pwm: renesas-tpu: Drop confusing registered messageGeert Uytterhoeven

2020-03-30pwm: imx27: Ensure clocks being on iff the PWM is onUwe Kleine-König
Up to now the .probe() function didn't enable clocks and relied on the core to call the .get_state() callback to have the clock running. The latter enabled the needed clocks and kept them running if the PWM wass enabled. This only works correctly if the .get_state() callback is called exactly once and this single call happens before unused clocks are disabled by the clk core. The former wasn't true for a short period while commit 01ccf903edd6 ("pwm: Let pwm_get_state() return the last implemented state") applied and not reverted yet and might become wrong in the future. The latter isn't true any more since commit cfc4c189bc70 ("pwm: Read initial hardware state at request time") which results in a running PWM being stopped at boot time if for example the consumer lives in a kernel module that is only loaded after the clk core disabled unused clocks. So ensure .probe() is left with the clocks on if the PWM is running and .get_state() disables everything it enabled.

2020-03-30pwm: imx27: Don't disable clocks at device remove timeUwe Kleine-König
The .remove() callback is not supposed to modify hardware state. This is in the responsibility of the PWM consumer. After the PWM was disabled the clocks are off (apart from a bug that is fixed in the next patch), so unbinding the driver either stops the PWM (which it should not) or disables already disabled clocks yielding warnings from the clk core. So just drop the call to disable the clocks. (Which BTW was also in the wrong order because the call makes the PWM unfunctional and so should have come only after pwmchip_remove()).

2020-03-30pwm: imx27: Fix clock handling in pwm_imx27_apply()Uwe Kleine-König
pwm_imx27_apply() enables the clocks if the previous PWM state was disabled. Given that the clocks are supposed to be left on iff the PWM is running, the decision to disable the clocks at the end of the function must not depend on the previous state. Without this fix the enable count of the two affected clocks increases by one whenever ->apply() changes from one disabled state to another.

2020-03-30PCI: Add support for root bus sizingIvan Kokshaysky
In certain cases we should be able to enumerate IO and MEM ranges of all PCI devices installed in the system, and then set respective host bridge apertures basing on calculated size and alignment. Particularly when firmware is broken and fails to assign bridge windows properly, like on Alpha UP1500 platform. Actually, almost everything is already in place, and required changes are minimal: - add "size_windows" flag to struct pci_host_bridge: when set, it instructs __pci_bus_size_bridges() to continue with the root bus; - in the __pci_bus_size_bridges() path: add checks for bus->self, as it can legitimately be null for the root bus.

2020-03-30PCI: Use ioremap(), not phys_to_virt() for platform ROMMikel Rychliski
On some EFI systems, the video BIOS is provided by the EFI firmware. The boot stub code stores the physical address of the ROM image in pdev->rom. Currently we attempt to access this pointer using phys_to_virt(), which doesn't work with CONFIG_HIGHMEM. On these systems, attempting to load the radeon module on a x86_32 kernel can result in the following: BUG: unable to handle page fault for address: 3e8ed03c #PF: supervisor read access in kernel mode #PF: error_code(0x0000) - not-present page *pde = 00000000 Oops: 0000 [#1] PREEMPT SMP CPU: 0 PID: 317 Comm: systemd-udevd Not tainted 5.6.0-rc3-next-20200228 #2 Hardware name: Apple Computer, Inc.

Instead of calling the helper function pci_platform_rom() which uses phys_to_virt(), call ioremap() directly on the pdev->rom. radeon_read_platform_bios() previously directly accessed an __iomem pointer. Avoid this by calling memcpy_fromio() instead of kmemdup(). pci_platform_rom() now has no remaining callers, so remove it.

2020-03-30rbd: enable multiple blk-mq queuesHannes Reinecke
Allocate one queue per CPU and get a performance boost from higher parallelism. Signed-off-by: Hannes Reinecke <hare@suse.de> Reviewed-by: Ilya Dryomov <idryomov@gmail.com> Signed-off-by: Ilya Dryomov <idryomov@gmail.com>
2020-03-30rbd: embed image request in blk-mq pduIlya Dryomov
Avoid making allocations for !IMG_REQ_CHILD image requests. Only IMG_REQ_CHILD image requests need to be freed now. Move the initial request checks to rbd_queue_rq(). Unfortunately we can't fill the image request and kick the state machine directly from rbd_queue_rq() because ->queue_rq() isn't allowed to block. Signed-off-by: Ilya Dryomov <idryomov@gmail.com>
2020-03-30rbd: acquire header_rwsem just once in rbd_queue_workfn()Ilya Dryomov
Currently header_rwsem is acquired twice: once in rbd_dev_parent_get() when the image request is being created and then in rbd_queue_workfn() to capture mapping_size and snapc. Introduce rbd_img_capture_header() and move image request allocation so that header_rwsem can be acquired just once. Signed-off-by: Ilya Dryomov <idryomov@gmail.com>
2020-03-30rbd: get rid of img_request_layered_clear()Ilya Dryomov
No need to clear IMG_REQ_LAYERED before destroying the request. Signed-off-by: Ilya Dryomov <idryomov@gmail.com>
2020-03-30rbd: kill img_request krefHannes Reinecke
The reference counter is never increased, so we can as well call rbd_img_request_destroy() directly and drop the kref. Signed-off-by: Hannes Reinecke <hare@suse.de> Reviewed-by: Ilya Dryomov <idryomov@gmail.com> Signed-off-by: Ilya Dryomov <idryomov@gmail.com>
2020-03-30rbd: remove barriers from img_request_layered_{set,clear,test}()Ilya Dryomov
IMG_REQ_LAYERED is set in rbd_img_request_create(), and tested and cleared in rbd_img_request_destroy() when the image request is about to be destroyed. The barriers are unnecessary. Signed-off-by: Ilya Dryomov <idryomov@gmail.com>

2020-03-30media: venus: firmware: Ignore secure call error on first resumeStanimir Varbanov
With the latest cleanup in qcom scm driver the secure monitor call for setting the remote processor state returns EINVAL when it is called for the first time and after another scm call auth_and_reset. The error returned from scm call could be ignored because the state transition is already done in auth_and_reset.
