* Dolgozói juttatások
From: Kapolcs Mátyás @ 2019-09-02 8:33 UTC (permalink / raw)
To: linux-arm-kernel
Üdvözlöm,
A cégét a konkurenciától megkülönböztető olyan különleges eszközök keresése során, amelyek a munkavállalók és a munkáltató számára egyaránt előnyösek, érdemes megfontolni a juttatásként adható kártyák alkalmazását.
A kártyán szereplő összeget az Ön alkalmazottai tetszőleges célra használhatják fel, és értékelni fogják munkáltatójuk elkötelezettségét.
Fizetésemelés helyett is kiváló alternatíva, hiszen alacsonyabb költségekkel jár, és a munkáltató szabályozhatja a kártyára töltendő összeget pl. a munkavállaló eredményei, szolgálati ideje, részvétele stb. alapján. A kártya bármikor lemondható.
Mikor alkalmas Önnek, hogy beszéljünk a kártyák alkalmazási lehetőségeiről az Önök cégénél?
Kapolcs Mátyás
Hungary Team Leader

by forwarding the struct device pointer from clock provider.

* [PATCH v1 0/3] Runtime PM support for MT8183 mcucfg clock provider

This series is based on v5.3-rc1 and Mediatek MT8183 scpsys support v7[1].
Since Runtime PM is supported in Common Clock Framework which keeps
clock controller's power domain enabled to ensure clock status accessing correctly.

As internal discussion, you mention that OVL and OVL_2L both has
bgclr_in function, so I think we should keep bgclr_in function for both
OVL and OVL_2L. And in crtc, always enable bgclr_in for comp[1], so code
here could be
if (i == 1)
mtk_ddp_comp_bgclr_in_on(comp);

* [PATCH net-next 10/13] net: stmmac: xgmac: Correct RAVSEL field interpretation
From: Jose Abreu @ 2019-09-02 8:01 UTC (permalink / raw)

In-Reply-To: <cover.1567410970.git.joabreu@synopsys.com>
RAVSEL means that only RX side is available for AVB features. As we use
both TX and RX features we need to check if RAVSEL is selected and
disable AVB if only RX side is available.

* [PATCH net-next 08/13] net: stmmac: Only consider RX error when HW Timestamping is not enabled
From: Jose Abreu @ 2019-09-02 8:01 UTC (permalink / raw)
To: netdev
Cc: Jose Abreu, Joao Pinto, Alexandre Torgue, linux-kernel,

In-Reply-To: <cover.1567410970.git.joabreu@synopsys.com>
Only consider that we have an error when HW Timestamping is not enabled
as this can give false positives due to the fact the RX Timestamping in
XGMAC and GMAC cores comes from context descriptors.

Maximum MTU for XGMAC cores is 16k thus the check for presence of XGMAC
shall be done first in order to assign correct value.

* [PATCH net-next 03/13] net: stmmac: Do not return error code in TC Initialization
From: Jose Abreu @ 2019-09-02 8:01 UTC (permalink / raw)
To: netdev
Cc: Jose Abreu, Joao Pinto, Alexandre Torgue, linux-kernel,

In-Reply-To: <cover.1567410970.git.joabreu@synopsys.com>
As we can still use the remaining TC callbacks, e.g. CBS. We should not
fail in the initialization only because RX Parser is not available.

* [PATCH net-next 12/13] net: stmmac: xgmac: Enable RX Jumbo frame support
From: Jose Abreu @ 2019-09-02 8:01 UTC (permalink / raw)
To: netdev
Cc: Jose Abreu, Joao Pinto, Alexandre Torgue, linux-kernel,
linux-stm32, Maxime Coquelin, Giuseppe Cavallaro, David S. Miller,
linux-arm-kernel
In-Reply-To: <cover.1567410970.git.joabreu@synopsys.com>
We are already doing it by default in the TX path so we can also enable
Jumbo Frame support in the RX path independently of MTU value.
Signed-off-by: Jose Abreu <joabreu@synopsys.com>

Thanks. I think the next two patches (15 and 16) should also be
fine for the asm-generic tree for 5.4. For patch 17 I'd rather have
all arch patches in first.
