This change adds MDP5 configuration for MSM8x36-based SoCs,
like MSM8936, 8939 and their APQ variants.
The configuration is based on MSM8916's, but adds some notable
features, like ad and pp blocks, along with some register
changes.
changes since v1:
- add an ad block
- add a second mixer @ 0x4700

There are other clocks than the standard ones, for instance
per process clocks. Therefore, being above the last standard clock
doesn't mean it is a bad clock. So, fallback to syscall instead

Hi,
This patch set tries to allow vendors to modify the WriteBooster flush policy.
In the same time, collect all customizable parameters to an unified structure
to make UFS driver more clean.
v1 -> v2:
- Squash patch [3] and [4]
- Remove a dummy "new line" in patch [3]
- Fix commit messag

runtime suspend if available WriteBooster buffer is less

Allow flush threshold for WriteBooster to be customizable by
vendors. To achieve this, make the value as a variable in struct
ufs_hba_variant_params.
Besides, use macro UFS_WB_BUF_REMAIN_PERCENT() instead to provide
more flexible usage of WriteBooster available buffer values.

In order to improve performance, we always disable STANDARD_AXI_MODE in

This patchset adds mt6779 iommu support.
mt6779 has two iommus, they are MM_IOMMU(M4U) and APU_IOMMU which used ARM
Short-Descriptor translation format.
The mt6779's MM_IOMMU-SMI and APU_IOMMU HW diagram is as below, it is only a
brief diagram:
EMI
1. Start from mt6779, INVLDT_SEL move to offset=0x2c, so we add
REG_MMU_INV_SEL_GEN2 definition and mt6779 uses it.
2. Change PROTECT_PA_ALIGN from 128 byte to 256 byte.
3. For REG_MMU_CTRL_REG register, we only need to change bit[2:0],
others bits keep default value, ex: enable victim tlb.
4
Some platforms(ex: mt6779) have a new register called by REG_MMU_WR_LEN
to improve performance.
This patch add this register definition.

For mt6779, MMU_INVLDT_SEL register's offset is changed from
0x38 to 0x2c, so we can put inv_sel_reg in the plat_data to
use it.
In addition, we renamed it to REG_MMU_INV_SEL_GEN1 and use it
before mt6779.

The max larb number that a iommu HW support is 8(larb0~larb7 in the below
diagram).
If the larb's number is over 8, we use a sub_common for merging
several larbs into one larb. At this case, we will extend larb_id:
bit[11:9] means common-id;
bit[8:7] means subcommon-id;
From these two variable, we

This patch adds description for MT6779 IOMMU.
MT6779 has two iommus, they are mm_iommu and apu_iommu which
both use ARM Short-Descriptor translation format.
In addition, mm_iommu and apu_iommu are two independent HW instance

I have got the impression that this patch series has got a questionable
mail threading.
Will it be helpful to resend it with a cover letter together with a few
adjustments for the corresponding change descriptions?

snprintf() returns the number of bytes that would be written,
which may be greater than the the actual length to be written.
show() methods should return the number of bytes printed into the
buffer. This is the return value of scnprintf().

In the probe function, in case of error, resources allocated in
'lp8788_setup_adc_channel()' must be released.
This can be achieved easily by using the devm_ variant of
'iio_channel_get()'.
This has the extra benefit to simplify the remove function and to axe the
'lp8788_release_adc_channel()' fun
