As with the previous platforms the power rail handling needs to be

This patch series implements following smp related features.
Some of the work has been inspired from ARM64.
1. Decouple linux logical cpu ids from hardware cpu id
2. Support cpu hotplug.
Tested on QEMU & HighFive Unleashed board with/without SMP enabled.
v1->v2:
1. Dropped cpu_ops patch.
2. Mov
This patch enable support for cpu hotplug in RISC-V.
In absence of generic cpu stop functions, WFI is used
to put the cpu in low power state during offline. An IPI
is sent to bring it out of WFI during online operation.

Setup the cpu_logical_map during boot. Moreover, every SBI call

Currently, both linux cpu id and hardware cpu id are same.
This is not recommended as it will lead to discontinuous cpu
indexing in Linux. Moreover, kdump kernel will run from CPU0
which would be absent if we follow existing scheme.

This series implements devm_kstrdup_const() together with some
prerequisite changes and uses it in pmc-atom driver.
v1 -> v2:
- fixed the changelog in the patch implementing devm_kstrdup_const()
- fixed the kernel doc
- moved is_kernel_rodata() to asm-generic/sections.h
- fixed constness
Bartosz
Provide a resource managed version of kstrdup_const(). This variant
internally calls devm_kstrdup() on pointers that are outside of
.rodata section and returns the string as is otherwise.
Also provide a corresponding version of devm_kfree().

Make devm_kfree() signature uniform with that of kfree(). To avoid
compiler warnings: cast p to (void *) when calling devres_destroy().

Use devm_kstrdup_const() in the pmc-atom driver. This mostly serves as
an example of how to use this new routine to shrink driver code.
While we're at it: replace a call to kcalloc() with devm_kcalloc().

When using DMA, if the DMA addr spans 128MB boundary, we have to split
the DMA transfer into two so that each one doesn't exceed the boundary.
patch1 adds adma_table_cnt to struct sdhci_host so that driver can
control the ADMA table count.
patch2 introduces adma_write_desc() hook to struct sdhci_o
The atmel hlcdc controller has nothing to do with these pins, so move
them to where they belong.

Hi!
Now that some other patches [1][2] have finally landed in -next, I
feel that it is time for this cleanup series that I have been hoarding

This patch adds adma_table_cnt member to struct sdhci_host to give more
flexibility to drivers to control the ADMA table count.
Default value of adma_table_cnt is set to (SDHCI_MAX_SEGS * 2 + 1).

The cd-gpios signal is assumed active-low by the driver, and the
cd-inverted property is needed if it is, in fact, active-high. Fix
this oversight.

Add this hook so that it can be overridden with driver specific
implementations. We also let the original sdhci_adma_write_desc()
accept &desc so that the function can set its new value. Then export
the function so that it could be reused by driver's specific
implementations.
