ata: libata-scsi: fix ata_dsm_trim_pages() kernel-docgrafted
make htmldocs fails with: Documentation/driver-api/libata:604: ./drivers/ata/libata-scsi.c:2301: ERROR: Unexpected indentation. [docutils] The Return: section of ata_dsm_trim_pages() ends its first sentence with a colon and continues with an indented bullet list. reStructuredText requires a blank line before an indented block, so docutils chokes on the list. Simply adding the missing blank line does not work either: Return: is a kernel-doc "special section", which is terminated by the first blank line, so the bullet list would end up in the Description section, detached from the sentence introducing it. Spell the two bounds out as prose instead, so that the Return: section stays self-contained. Documentation-only change. Fixes: e64e6b5dc867 ("ata: libata-scsi: scale DSM TRIM payload by MAX PAGES PER DSM COMMAND") Reported-by: Thomas Huth <thuth@redhat.com> Closes: https://lore.kernel.org/linux-ide/b0a0b8e8-cc4f-4c7b-8bc5-fee0712d405a@redhat.com/ Reviewed-by: Damien Le Moal <dlemoal@kernel.org> Reviewed-by: Thomas Huth <thuth@redhat.com> Link: https://lore.kernel.org/r/20260916130031.29990-2-cassel@kernel.org Signed-off-by: Niklas Cassel <cassel@kernel.org>

+* Nios II Processor Binding
+
+This binding specifies what properties available in the device tree
+representation of a Nios II Processor Core.
+
+Users can use sopc2dts tool for generating device tree sources (dts) from a
+Qsys system. See more detail in: http://www.alterawiki.com/wiki/Sopc2dts
+
+Required properties:
+
+- compatible: Compatible property value should be "altr,nios2-1.0".
+- reg: Contains CPU index.
+- interrupt-controller: Specifies that the node is an interrupt controller
+- #interrupt-cells: Specifies the number of cells needed to encode an
+ interrupt source, should be 1.
+- clock-frequency: Contains the clock frequency for CPU, in Hz.
+- dcache-line-size: Contains data cache line size.
+- icache-line-size: Contains instruction line size.
+- dcache-size: Contains data cache size.
+- icache-size: Contains instruction cache size.
+- altr,pid-num-bits: Specifies the number of bits to use to represent the process
+ identifier (PID).
+- altr,tlb-num-ways: Specifies the number of set-associativity ways in the TLB.
+- altr,tlb-num-entries: Specifies the number of entries in the TLB.
+- altr,tlb-ptr-sz: Specifies size of TLB pointer.
+- altr,has-mul: Specifies CPU hardware multiply support, should be 1.
+- altr,has-mmu: Specifies CPU support MMU support, should be 1.
+- altr,has-initda: Specifies CPU support initda instruction, should be 1.
+- altr,reset-addr: Specifies CPU reset address
+- altr,fast-tlb-miss-addr: Specifies CPU fast TLB miss exception address
+- altr,exception-addr: Specifies CPU exception address
+
+Optional properties:
+- altr,has-div: Specifies CPU hardware divide support
+- altr,implementation: Nios II core implementation, this should be "fast";
+
+Example:
+
+cpu@0 {
+ device_type = "cpu";
+ compatible = "altr,nios2-1.0";
+ reg = <0>;
+ interrupt-controller;
+ #interrupt-cells = <1>;

+ dcache-line-size = <32>;
+ icache-line-size = <32>;
+ dcache-size = <32768>;
+ icache-size = <32768>;
+ altr,implementation = "fast";
+ altr,pid-num-bits = <8>;
+ altr,tlb-num-ways = <16>;
+ altr,tlb-num-entries = <128>;
+ altr,tlb-ptr-sz = <7>;
+ altr,has-div = <1>;
+ altr,has-mul = <1>;
+ altr,reset-addr = <0xc2800000>;
+ altr,fast-tlb-miss-addr = <0xc7fff400>;
+ altr,exception-addr = <0xd0000020>;
+ altr,has-initda = <1>;
+ altr,has-mmu = <1>;
