HyperFlash devices fail to probe:

In HyperFlash or Octal-SPI Flash mode, the Transfer Data Enable bits
(SPIDE) in the Manual Mode Enable Setting Register (SMENR) are derived
from half of the transfer size, cfr. the rpcif_bits_set() helper
function.  However, rpcif_reg_{read,write}() does not take the bus size
into account, and does not double all Manual Mode Data Register access
sizes when communicating with a HyperFlash or Octal-SPI Flash device.

Fix this, and avoid the back-and-forth conversion between transfer size
and Transfer Data Enable bits, by explicitly storing the transfer size
in struct rpcif, and using that value to determine access size in
rpcif_reg_{read,write}().

Enforce that the "high" Manual Mode Read/Write Data Registers
(SM[RW]DR1) are only used for 8-byte data accesses.

ARM: dts: am33xx-l4: Add missing touchscreen clock properties

When adding support for TI magadc (Magnetic Stripe Reader and ADC), the
MFD driver common to the touchscreen and the ADC got updated to ease the
insertion of a new DT node for the ADC, with its own compatible, clocks,
etc. Commit 235a96e92c16 ("mfd: ti_am335x_tscadc: Don't search the tree
for our clock") removed one compatible specific information which was
the clock name, because the clock was looked up from scratch in the DT
while this hardware block was only fed by a single clock, already
defined and properly filled in the DT.

Problem is, this change was only validated with an am437x-based board,
where the clocks are effectively correctly defined and referenced. But
on am33xx, the ADC clock is also correctly defined but is not referenced
with a clock phandle as it ought to be.

The touchscreen bindings clearly state that the clocks/clock-names
properties are mandatory, but they have been forgotten in one DTSI. This
was probably not noticed in the first place because of the clock
actually existing and the clk_get() call going through all the tree
anyway.

Add the missing clock phandles in the am33xx touchscreen description.

Fix the problem by describing the MCLK pinctrl inside the codec

Commit 3f6634d997db ("iommu: Use right way to retrieve iommu_ops") started
triggering a NULL pointer dereference for some omap variants:

__iommu_probe_device from probe_iommu_group+0x2c/0x38

This is caused by omap iommu probe returning 0 instead of ERR_PTR(-ENODEV)

Looks like the regression already happened with an earlier commit

2 years agofirmware: arm_scmi: Remove clear channel call on the TX channel
Cristian Marussi [Thu, 24 Feb 2022 15:24:04 +0000 (15:24 +0000)]
firmware: arm_scmi: Remove clear channel call on the TX channel

On SCMI transports whose channels are based on a shared resource the TX
channel area has to be acquired by the agent before placing the desired
command into the channel and it will be then relinquished by the platform
once the related reply has been made available into the channel.
On an RX channel the logic is reversed with the platform acquiring the
channel area and the agent reliquishing it once done by calling the
scmi_clear_channel() helper.

As a consequence, even in case of error, the agent must never try to clear
a TX channel from its side: restrict the existing clear channel call on the
the reply path only to delayed responses since they are indeed coming from
the RX channel.
