While the Hardware User Manual does not document the maximum time needed for modifying bits in the MSIOF Control Register, experiments on R-Car Gen2/Gen3 and SH-Mobile AG5 revealed the following typical modification times for the various bits: - CTR.TXE and CTR.RXE: no delay, - CTR.TSCKE: less than 10 ns, - CTR.TFSE: up to a few hundred ns (depending on SPI transfer clock, i.e. less for faster transfers). There are no reasons to believe these figures are different for SH-MobileR2 SoCs (SH7723/SH7724). Hence the minimum busy-looping delay of 10 µs is excessive. Reduce the delay per loop iteration from 10 to 1 us, and the maximum delay from 1000 to 100 µs.

Convert the Arm pl022 binding to DT schema format. The clock binding was missing, so it is added to the schema. It really should be required as well, but there are some platforms (spear) not yet using DT clock binding.

The BCM2835 SPI driver still sets the "direction" member in struct dma_slave_config even though it was deprecated five years ago with commit d9ff958b ("dmaengine: Mark the struct dma_slave_config direction field deprecated") and is no longer evaluated by the BCM2835 DMA driver since commit 00648f4d ("dmaengine: bcm2835: remove dma_slave_config direction usage"). Drop the superfluous assignment. No functional change intended.

Currently on panic, kernel will lower the loglevel and print out pending printk msg only with console_flush_on_panic(). Add an option for users to configure the "panic_print" to replay all dmesg in buffer, some of which they may have never seen due to the loglevel setting, which will help panic debugging .

Since commit 54c7a891 ("initramfs: free initrd memory if opening /initrd.image fails"), the kernel has unconditionally attempted to free the initrd even if it doesn't exist. In the non-existent case this causes a boot-time splat if CONFIG_DEBUG_VIRTUAL is enabled due to a call to virt_to_phys() with a NULL address. Instead we should check that the initrd actually exists and only attempt to free it if it does.

synchronize_rcu() didn't wait for call_rcu() callbacks, so inode wb switch may not go to the workqueue after synchronize_rcu(). Thus previous scheduled switches was not finished even flushing the workqueue, which will cause a NULL pointer dereferenced followed below. VFS: Busy inodes after unmount of vdd. Self-destruct in 5 seconds. Have a nice day... BUG: unable to handle kernel NULL pointer dereference at 0000000000000278 evict+0xb3/0x180 iput+0x1b0/0x230 inode_switch_wbs_work_fn+0x3c0/0x6a0 worker_thread+0x4e/0x490 ? process_one_work+0x410/0x410 kthread+0xe6/0x100 ret_from_fork+0x39/0x50 Replace the synchronize_rcu() call with a rcu_barrier() to wait for all pending callbacks to finish. And inc isw_nr_in_flight after call_rcu() in inode_switch_wbs() to make more sense.
