staging: nvec: fix block comment style in nvec_interrupt()

2026-02-24T18:11:42+00:00

Fix multi-line block comment to use the preferred kernel comment style
with leading asterisks on each line and a trailing */ on a separate
line, as reported by checkpatch.pl.

staging: nvec: propagate error codes in tegra_nvec_probe()

2026-02-23T14:44:44+00:00

Several error paths in tegra_nvec_probe() return -ENODEV instead of
propagating the actual error code from the called function. This
prevents probe deferral from working correctly when a dependency
(clock, IRQ) is not yet available.

Fix this for platform_get_irq(), devm_clk_get(), and
devm_request_irq() by propagating their return values. Use
dev_err_probe() for the latter two to suppress log messages during
deferred probing.

The remaining -ENODEV returns for missing device tree node and
slave-addr property are left unchanged as those are permanent
configuration errors unrelated to probe deferral.

staging: nvec: apply udelay only after the first byte has been sent

2026-01-11T12:53:56+00:00

Due to a HW bug in the Tegra20 SoC a udelay needs to be added after
the first byte has been sent to the EC (I2C master). Move it to the
correct position and add a comment that it should not be replaced by
usleep_range.

staging: Switch back to struct platform_driver::remove()

2024-10-09T09:54:53+00:00

After commit 0edb555a65d1 ("platform: Make platform_driver::remove()
return void") .remove() is (again) the right callback to implement for
platform drivers.

Convert all staging drivers to use .remove(), with the eventual goal to
drop struct platform_driver::remove_new(). As .remove() and .remove_new()
have the same prototypes, conversion is done by just changing the structure
member name in the driver initializer.

staging: nvec: Use IRQF_NO_AUTOEN flag in request_irq()

2024-09-13T05:30:23+00:00

disable_irq() after request_irq() still has a time gap in which
interrupts can come. request_irq() with IRQF_NO_AUTOEN flag will
disable IRQ auto-enable when request IRQ.

staging: nvec: Capitalize outputs to match the rest of the driver

2024-07-31T06:19:09+00:00

Noticing that some messages were capitalized and some weren't, I
capitalized them to match the rest. This makes the messages relatively
easier to understand for an end user, and reduces confusion about
capitalization. A comment was also capitalized.

staging: nvec: make i2c controller register writes robust

2024-06-04T11:26:36+00:00

The i2c controller needs to read back the data written to its registers.
This way we can avoid the long delay in the interrupt handler.

In case we just want to submit a message to the EC but are not
