50 MHz is an incredibly common clock rate for SD cards to run at. It's "high speed" mode in SD (not very fast these days, but it used to be) or: #define HIGH_SPEED_MAX_DTR 50000000 If we don't support this then older "high speed" cards can only run at 25 MHz or at half their normal speed. There doesn't seem to be any reason to skip this clock rate, so add it. Fixes: 17269568 ("clk: qcom: Add Global Clock controller (GCC) driver for SC7180") Signed-off-by:

I would repeat the same commit message that was in commit 5e4b7e82 ("clk: qcom: gcc-sdm845: Use floor ops for sdcc clks") but it seems silly to do so when you could just go read that commit. NOTE: this is actually extra terrible because we're missing the 50 MHz rate in the table (see the next patch AKA ("clk: qcom: gcc-sc7180: Add 50 MHz clock rate for SDC2")). That means then when you run an older SD card it'll try to clock it at 100 MHz when it's only specced to run at 50 MHz max. As you can probably guess that doesn't work super well. Signed-off-by:

Let's call pm_runtime_get() here instead of calling the PM clk APIs directly. This avoids a compilation problem on CONFIG_PM=n where the pm_clk_runtime_{resume,suspend}() functions don't exist and covers the intent, i.e. enable the clks for this device so we can program PLL settings.

The sc7180 lpass clock driver manages two different devices. These two devices were tangled together, using one probe and a lookup to figure out the real probe. I think it's cleaner to really separate the probe for these two devices since they're really different things, just both managed by the same driver. Signed-off-by:

Pull random32 updates from Willy Tarreau: "Make prandom_u32() less predictable. This is the cleanup of the latest series of prandom_u32 experimentations consisting in using SipHash instead of Tausworthe to produce the randoms used by the network stack. The changes to the files were kept minimal, and the controversial commit that used to take noise from the fast_pool (f227e3ec) was reverted. Instead, a dedicated "net_rand_noise" per_cpu variable is fed from various sources of activities (networking, scheduling) to perturb the SipHash state using fast, non-trivially predictable data, instead of keeping it fully deterministic. The goal is essentially to make any occasional memory leakage or brute-force attempt useless. The resulting code was verified to be very slightly faster on x86_64 than what is was with the controversial commit above, though this remains barely above measurement noise. It was also tested on i386 and arm, and build- tested only on arm64" Link: https://lore.kernel.org/netdev/20200808152628.GA27941@SDF.ORG/ * tag '20201024-v4-5.10' of git://git.kernel.org/pub/scm/linux/kernel/git/wtarreau/prandom: random32: add a selftest for the prandom32 code random32: add noise from network and scheduling activity random32: make prandom_u32() output unpredictable
