/dev/nvram was never meant to be used alongside the RTC CMOS driver from drivers/rtc as it already expose the NVRAM through another interface.. Anyway, the last defconfig to enable it properly was removed in 2010 so prevent ARM users from selecting it.

This change populates device tree nodes for scanned FSI slaves and engines. If the master populates ->of_node of the FSI master device, we'll look for matching slaves, and under those slaves we'll look for matching engines. This means that FSI drivers will have their ->of_node pointer populated if there's a corresponding DT node, which they can use for further device discover. Presence of device tree nodes is optional, and only required for fsi device drivers that need extra properties, or subordinate devices, to be enumerated.

This change introduces an 'external mode' for GPIO-based FSI masters, allowing the clock and data lines to be driven by an external source. For example, external mode is selected by a user when an external debug device is attached to the FSI pins. To do this, we need to set specific states for the trans, mux and enable GPIOs, and prevent access to clk & data from the FSI core code (by returning EBUSY). External mode is controlled by a sysfs attribute, so add the relevant information to Documentation/ABI/ Signed-off-by: Jeremy Kerr <[email protected]> Reviewed-by: Joel Stanley <[email protected]> Signed-off-by: Joel Stanley <[email protected]> Signed-off-by: Greg Kroah-Hartman <[email protected]>

2018-03-14coresight: etm4x: Fix bit shiftingBo Yan1-2/+2
ctxid_pid and vmid_val in config are of type u64. When an integer 0xFF is being left shifted more than 32 bits, the behavior is undefined. The fix is to specify 0xFF as an unsigned long.

2018-03-14coresight: Use %px to print pcsr instead of %pLeo Yan1-1/+1
Commit ad67b74d2469 ("printk: hash addresses printed with %p") lets printk specifier %p to hash all addresses before printing, this was resulting in the high 32 bits of pcsr can only output zeros. So module cannot completely print pc value and it's pointless for debugging purpose. This patch fixes this by using %px to print pcsr instead.

While here, remove init.h inclusion since we are not using it directly and module.h will do this for us. No functional changes intended.

2018-03-14parport: Switch to use module_pci_driver() macroAndy Shevchenko1-15/+1
Eliminate some boilerplate code by using module_pci_driver() instead of init/exit, moving the salient bits from init into probe.

dev_warn() will print device name with associated driver, no need to keep this open coded. While here, adjust indentation in the rest of dev_dbg() calls.

2018-03-14parport: Convert to use managed functions pcim_* and devm_*Andy Shevchenko1-10/+5
This makes the error handling much more simpler than open-coding everything and in addition makes the probe function smaller an tidier.
