Neither the m25_div_clk nor the m250_div_clk or m250_mux_clk are used in RMII mode. The m25_div_clk output is routed to the RGMII PHY's "RGMII clock". This means that we don't need to configure the clocks in RMII mode. The driver however did this - with no effect since the clocks are not routed to

Meson8b only supports MPLL2 as clock input. The rate of the MPLL2 clock set by Odroid-C1's u-boot is close to (but not exactly) 500MHz. The exact rate is 52394Hz, which is calculated in drivers/clk/meson/clk-mpll.c using the following formula: DIV_ROUND_UP_ULL((u64)parent_rate * SDM_DEN,

[RFT net-next v4 5/5] net: stmmac: dwmac-meson8b: propagate rate changes to the parent clock

On Meson8b the only valid input clock is MPLL2. The bootloader configures that to run at 52394Hz which cannot be divided evenly down to 125MHz using the m250_div clock. Currently the common clock framework chooses a m250_div of 2 - with the internal fixed "divide by 10" this results in a RGMII

[PATCH] nl80211: take RCU read lock when calling ieee80211_bss_get_ie()

As ieee80211_bss_get_ie() derefences an RCU, it needs to be called with rcu_read_lock held. Fixes: 44905265bc15 ("nl80211: don't expose wdev->ssid for most interfaces") Signed-off-by: Dominik Brodowski --- This patch fixes the regression I reported in the last couple

[PATCH 1/2] sh_eth: gather all TSU init code in one place

The sh_eth_cpu_data::chip_reset() method always resets using ARSTR and this register is always located at the start of the TSU register region. Therefore, we can only call this method if we know TSU is there and thus simplify the probing code a bit... Signed-off-by: Sergei Shtylyov

[PATCH 2/2] sh_eth: get Ether port # only when needed

The dual-port Ether configurations always have a shared TSU to e.g. pass the packets between those ports. With the TSU init. code gathered under the single *if*, we now can only get the port # from 'platform_device::id' only when we actually need it (and not recalculate it each time)...

[PATCH v2 net-next 1/5] l2tp: fix switch default error handling in l2tp_nl_cmd_session_create()

Although this issue is harmless since that code path is protected by the check on l2tp_nl_cmd_ops[]/l2tp_nl_cmd_ops[]->session_create(), fix error handling for L2TP_PWTYPE_IP/default case in l2tp_nl_cmd_session_create() Signed-off-by: Lorenzo Bianconi ---

[PATCH v2 net-next 2/5] l2tp: double-check l2specific_type provided by userspace

Add sanity check on l2specific_type provided by userspace in l2tp_nl_cmd_session_create() since just L2TP_L2SPECTYPE_DEFAULT and L2TP_L2SPECTYPE_NONE are currently supported. Moreover do not always initialize l2specific_type if userspace requests a given l2-specific sublayer type Signed-off-by:

[PATCH v2 net-next 0/5] l2tp: set l2specific_len based on l2specific_type

Do not rely on l2specific_len value provided by userspace but set sublayer length according to l2specific_type. Fix a harmless issue in the switch default case in l2tp_nl_cmd_session_create(). Changes since v1: - remove l2specific_len parameter - add sanity check on l2specific_type provided by

[PATCH v2 net-next 3/5] l2tp: remove l2specific_len dependency in l2tp_core

Remove l2specific_len dependency while building l2tpv3 header or parsing the received frame since default L2-Specific Sublayer is always four bytes long and we don't need to rely on a user supplied value. Moreover in l2tp netlink code there are no sanity checks to enforce the relation between
