[PATCH 1/1] ASoC: fsl: fsl_ssi: Add dev_err_probe if PCM DMA init fails

2024-03-14 Thread Alexander Stein 
This happens especially if this driver is built-in, but SDMA driver
is configured as module.

These patches could be squashed, but I opted for separation this patch
is the actual functional change. Patch 1 is just preparation.

[PATCH v3 10/10] ARM: add multi_v7_lpae_defconfig

2023-01-24 Thread Alexander Stein 
From: Nicolas Saenz Julienne 

The only missing configuration option preventing us from using
multi_v7_defconfig with the Raspberry Pi 4 is ARM_LPAE. It's needed as
the PCIe controller found on the SoC depends on 64bit addressing, yet
can't be included as not all v7 boards support LPAE.

Introduce multi_v7_lpae_defconfig, built off multi_v7_defconfig, which will
avoid us having to duplicate and maintain multiple similar configurations.

Needless to say the Raspberry Pi 4 is not the only platform that can
benefit from this new configuration.

Changes in v3:
* As per Arnd's suggestion add CONFIG_VMSPLIT_2G to lpae.config fragment
* List multi_v7_lpae_defconfig target in 'make help' as well

Unfortunately the list of defconfigs is autogenerated, so this new
(explicit) target doesn't fit into this list. Therefore it's added to
'archhelp' instead.

[PATCH v2 10/10] ARM: add multi_v7_lpae_defconfig

2023-01-20 Thread Alexander Stein 
From: Nicolas Saenz Julienne 

The only missing configuration option preventing us from using
multi_v7_defconfig with the Raspberry Pi 4 is ARM_LPAE. It's needed as
the PCIe controller found on the SoC depends on 64bit addressing, yet
can't be included as not all v7 boards support LPAE.

Introduce multi_v7_lpae_defconfig, built off multi_v7_defconfig, which will
avoid us having to duplicate and maintain multiple similar configurations.

Needless to say the Raspberry Pi 4 is not the only platform that can
benefit from this new configuration.

[PATCH v2 09/10] kbuild: Add config fragment merge functionality

2023-01-20 Thread Alexander Stein 
From: Nicolas Saenz Julienne 

So far this function was only used locally in powerpc, some other
architectures might benefit from it. Move it into
scripts/Makefile.defconf.

[PATCH v2 00/10] TQMLS1021A support

2023-01-20 Thread Alexander Stein 
Hi,

this is the second round of this series to add support for the TQMLS1021A
using the MBLS1021A mainboard.
The changelog is included in the individual patches but the most notable
one is picking up the old patch series for adding lpae config snippet
support.

Best regards,
Alexander

Okay, I was just wondering why the timeout is dependant on the timer tick. 
That didn't seem obvious to me.
Rethinking about this, I would rather replace those lines with msleep instead.

Best regards,

[PATCH 1/1] serial/uuc_uart: Set shutdown timeout to CONFIG_HZ independent 2ms

2016-12-05 Thread Alexander Stein 
schedule_timeout takes a timeout in jiffies resolution. So pass 2ms
as a converted jiffies value. This makes the timeout independent of
CONFIG_HZ.

This is stored in port.uartclk during probe. Respecting the 16x
