pmdomain: renesas: r8a77980-sysc: CR7 must be always on

2024-03-01T12:13:34+00:00

[ Upstream commit f0e4a1356466ec1858ae8e5c70bea2ce5e55008b ]

The power domain containing the Cortex-R7 CPU core on the R-Car V3H SoC
must always be in power-on state, unlike on other SoCs in the R-Car Gen3
family.  See Table 9.4 "Power domains" in the R-Car Series, 3rd
Generation Hardware User’s Manual Rev.1.00 and later.

Fix this by marking the domain as a CPU domain without control
registers, so the driver will not touch it.

soc: qcom: llcc: Handle a second device without data corruption

2023-11-20T09:30:12+00:00

[ Upstream commit f1a1bc8775b26345aba2be278118999e7f661d3d ]

Usually there is only one llcc device. But if there were a second, even
a failed probe call would modify the global drv_data pointer. So check
if drv_data is valid before overwriting it.

[ Upstream commit a0e72a5ba48ae9c6449a32130d74506a854b79d2 ]

The cleaning up was done without changing the driver file name
to ensure a cleaner bisect. Change the file name now to facilitate
making the driver generic in subsequent patch.

A single file should suffice the need to program the llcc for

soc: qcom: qmi_encdec: Restrict string length in decode

2023-09-23T08:59:57+00:00

commit 8d207400fd6b79c92aeb2f33bb79f62dff904ea2 upstream.

The QMI TLV value for strings in a lot of qmi element info structures
account for null terminated strings with MAX_LEN + 1. If a string is
actually MAX_LEN + 1 length, this will cause an out of bounds access
when the NULL character is appended in decoding.

soc/fsl/qe: fix usb.c build errors

2023-07-27T06:37:14+00:00

[ Upstream commit 7b1a78babd0d2cd27aa07255dee0c2d7ac0f31e3 ]

Fix build errors in soc/fsl/qe/usb.c when QUICC_ENGINE is not set.
This happens when PPC_EP88XC is set, which selects CPM1 & CPM.
When CPM is set, USB_FSL_QE can be set without QUICC_ENGINE
being set. When USB_FSL_QE is set, QE_USB deafults to y, which
causes build errors when QUICC_ENGINE is not set. Making
QE_USB depend on QUICC_ENGINE prevents QE_USB from defaulting to y.

Fixes these build errors:

ARM: ux500: do not directly dereference __iomem

2023-01-18T10:41:46+00:00

commit 65b0e307a1a9193571db12910f382f84195a3d29 upstream.

Sparse reports that calling add_device_randomness() on `uid` is a
violation of address spaces. And indeed the next usage uses readl()
properly, but that was left out when passing it toadd_device_
randomness(). So instead copy the whole thing to the stack first.

soc: qcom: Select REMAP_MMIO for LLCC driver

commit 5d2fe2d7b616b8baa18348ead857b504fc2de336 upstream.

LLCC driver uses REGMAP_MMIO for accessing the hardware registers. So
select the dependency in Kconfig. Without this, there will be errors
while building the driver with COMPILE_TEST only:

ERROR: modpost: "__devm_regmap_init_mmio_clk" [drivers/soc/qcom/llcc-qcom.ko] undefined!

a pairing decrement is needed on the error handling path to
keep it balanced according to context.
