Here contained are two fixes for the mediatek and the imx-tpm driver. Both are already old but (v4.12-rc1 and v5.2-rc1 respectively) given it's still very early in the development cycle I consider them fine to go in. The mediatek issue is that both period and duty_cycle were configured to higher values than requested. For most applications the period part is no tragedy, but a PWM that is configured for duty_cycle = 0 should really emit a constant inactive signal. That was noticed by an LED not being completely off in this case. For the imx-tpm PWM driver the fixed issue is that the first period is quite a bit too long under some circumstances. So it might take up to UINT32_MAX << 7 clock ticks until the PWM starts toggling. With an assumed input clock rate of 166 MHz (completely made up) that's 55 minutes. -----BEGIN PGP SIGNATURE----- iQEzBAABCgAdFiEEP4GsaTp6HlmJrf7Tj4D7WH0S/k4FAmiLNDwACgkQj4D7WH0S /k6zDQf9Fa2BdzsF82IwyYy4oQBOb1KIW7YzP8CwHzRBITnq09EA2zRV8cGE7Ohk c/QMi9ILcMYwRXKk3kJIqGUY5HYcPX2yh21pNTatBTh47OJZnoBV1tbDEQbCLM55 tS3fd3CduHdTP05j1X5QDEvsEhb9xKbUvAZ2z0jMX/6aOE+wMG1hq46GTQfAmewA pbyaGQk+0C1E4qONJ2eJz7zmkrPRa++EWusiOy7zfgQyf9GuX/PHftIiemabq+fP +WG4+nxVafHhmKg1b7JoGixXhHobTOiWnKTpBJCcvrqgIIfOgiDxb28bxPZibi04 IDZNZUyXlnRikENbF7mfP1ICL1ygLA== =CYER -----END PGP SIGNATURE----- Merge tag 'pwm/for-6.17-rc1-fixes' of git://git.kernel.org/pub/scm/linux/kernel/git/ukleinek/linux Pull pwm fixes from Uwe Kleine-König: "Two fixes for the mediatek and the imx-tpm driver.

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the reStructuredText markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
