thermal/drivers/sprd: Fix raw temperature clamping in sprd_thm_rawdata_to_temp

2026-06-01T15:29:24+00:00

commit b3414148bbc1f9cd56217e58a558c6ac4fd1b4a6 upstream. The raw temperature data was never clamped to SPRD_THM_RAW_DATA_LOW or SPRD_THM_RAW_DATA_HIGH because the return value of clamp() was not used. Fix this by assigning the clamped value to 'rawdata'. Casting SPRD_THM_RAW_DATA_LOW and SPRD_THM_RAW_DATA_HIGH to u32 is also redundant and can be removed.

thermal/int340x_thermal: handle data_vault when the value is ZERO_SIZE_PTR

2026-06-01T15:29:14+00:00

commit 7931e28098a4c1a2a6802510b0cbe57546d2049d upstream. In some case, the GDDV returns a package with a buffer which has zero length. It causes that kmemdup() returns ZERO_SIZE_PTR (0x10). Then the data_vault_read() got NULL point dereference problem when accessing the 0x10 value in data_vault. [ 71.024560] BUG: kernel NULL pointer dereference, address: 0000000000000010 This patch uses ZERO_OR_NULL_PTR() for checking ZERO_SIZE_PTR or NULL value in data_vault.

thermal: sysfs: Return ENODATA instead of EAGAIN for reads

2025-08-28T14:22:41+00:00

[ Upstream commit 1a4aabc27e95674837f2e25f4ef340c0469e6203 ] According to POSIX spec, EAGAIN returned by read with O_NONBLOCK set means the read would block. Hence, the common implementation in nonblocking model will poll the file when the nonblocking read returns EAGAIN. However, when the target file is thermal zone, this mechanism will totally malfunction because thermal zone doesn't implement sysfs notification and thus the poll will never return. For example, the read in Golang implemnts such method and sometimes hangs at reading some thermal zones via sysfs. Change to return -ENODATA instead of -EAGAIN to userspace.

thermal/drivers/qcom/tsens: Update conditions to strictly evaluate for IP v2+

2025-06-27T10:04:17+00:00

[ Upstream commit e3f90f167a49902cda2408f7e91cca0dcfd5040a ] TSENS v2.0+ leverage features not available to prior versions such as updated interrupts init routine, masked interrupts, and watchdog. Currently, the checks in place evaluate whether the IP version is greater than v1 which invalidates when updates to v1 or v1 minor versions are implemented. As such, update the conditional statements to strictly evaluate whether the version is greater than or equal to v2 (inclusive).

thermal/drivers/rockchip: Add missing rk3328 mapping entry

2025-05-02T05:40:56+00:00

commit ee022e5cae052e0c67ca7c5fec0f2e7bc897c70e upstream. The mapping table for the rk3328 is missing the entry for -25C which is found in the TRM section 9.5.2 "Temperature-to-code mapping". NOTE: the kernel uses the tsadc_q_sel=1'b1 mode which is defined as: 4096-

. Whereas the table in the TRM gives the code
      "3774" for -25C, the kernel uses 4096-3774=322.

[Dragan Simic] : "After going through the RK3308 and RK3328 TRMs, as
  well as through the downstream kernel code, it seems we may have
  some troubles at our hands.  Let me explain, please.

  To sum it up, part 1 of the RK3308 TRM v1.1 says on page 538 that
  the equation for the output when tsadc_q_sel equals 1 is (4096 -
  tsadc_q), while part 1 of the RK3328 TRM v1.2 says that the output
  equation is (1024 - tsadc_q) in that case.

  The downstream kernel code, however, treats the RK3308 and RK3328
  tables and their values as being the same.  It even mentions 1024 as
  the "offset" value in a comment block for the rk_tsadcv3_control()
  function, just like the upstream code does, which is obviously wrong
  "offset" value when correlated with the table on page 544 of part 1
  of the RK3308 TRM v1.1.

  With all this in mind, it's obvious that more work is needed to make
  it clear where's the actual mistake (it could be that the TRM is
  wrong), which I'll volunteer for as part of the SoC binning project.
  In the meantime, this patch looks fine as-is to me, by offering
  what's a clear improvement to the current state of the upstream
  code"

thermal: int340x: Add NULL check for adev
2025-04-10T12:30:55+00:00
[ Upstream commit 2542a3f70e563a9e70e7ded314286535a3321bdb ]

Not all devices have an ACPI companion fwnode, so adev might be NULL.
This is similar to the commit cd2fd6eab480
("platform/x86: int3472: Check for adev == NULL").

Add a check for adev not being set and return -ENODEV in that case to
avoid a possible NULL pointer deref in int3402_thermal_probe().

Note, under the same directory, int3400_thermal_probe() has such a
check.
